* For small amplitude signals, PM is similar to amplitude modulation ( AM ) and exhibits its unfortunate doubling of baseband bandwidth and poor efficiency.

The front end of an SSB receiver is similar to that of an AM or FM receiver, consisting of a superheterodyne RF front end that produces a frequency-shifted version of the radio frequency ( RF ) signal within a standard intermediate frequency ( IF ) band.

Modulation transformers in AM transmitters are very similar.

This can therefore be used in a DC power supply, and is also used as a demodulator of amplitude modulated ( AM ) radio signals and similar functions.

In Arthur – Merlin protocols, Babai defined a similar class AM which allowed f ( n ) rounds, but he put one extra condition on the machine: the verifier must show the prover all the random bits it uses in its computation.

This, similar to the AM, incorporates a Flexitor front suspension, and a rear suspension based on the unified rear triangle principle.

* Cancellation of signal: In addition, many AM stations, including but not limited to the clear channel stations, often experience cancellation of their own signals within the inner and outer fringes of their normal groundwave coverage areas at nighttime due to the stations ' individual skywave signals reaching the listeners ' receivers at or near equal strength to the stations ' individual groundwave signals ; this phenomenon is very similar to the multipath interference experienced on FM Radio in the VHF band within mountainous regions and urban areas due to signals bouncing off of mountains, buildings, and other structures, except that the groundwave-skywave cancellation occurs almost exclusively at nighttime when skywave propagation is present.

Domains within the. am ccTLD enjoy popularity due to the connection to AM radio ( similar to the. fm and. tv ccTLDs ), and the ability to form English words ending in " am " — e. g. the mobile photo sharing service Instagram uses the Armenian domain name Instagr. am.

Personal two-way radios are also sometimes combined with other electronic devices ; Garmin's Rino series combine a GPS receiver in the same package as an FRS / GMRS walkie-talkie ( allowing Rino users to transmit digital location data to each other ) Some personal radios also include receivers for AM and FM broadcast radio and, where applicable, NOAA Weather Radio and similar systems broadcasting on the same frequencies.

On Monday, January 28, 2008 at 5: 45 AM, The Regular Guys announced the debut of " Rock 100. 5 ", carrying a radio format similar to their previous station WKLS ( formerly " 96 Rock "), which itself changed formats to active rock as " Project 9-6-1 ".

Germain hosted a similar show as Mr. KABC for ten years before leaving KABC for KTLK ( AM 1150 ) and now broadcasts using both his name and a new shortened " Mr. K ." moniker.

The original construction permit for the station bore the call letters WQTI ( similar to Mulholland's easy listening-formatted AM station, 560 WQTE ( now WRDT ), but the station was never on the air with those calls.

The 6AV6 was a miniature repackaging ( with just a single cathode ) of the triode and twin diodes from the octal 6SQ7 ( a double-diode triode used in AM radios ), which itself was very similar to the older type 75 triode-diode dating from 1930.

The digital radio signal received on a conventional AM receiver tuned to an adjacent channel sounds like a large waterfall or similar white noise-like hiss, as can be heard in the audio soundclip referenced in the previous sentence.

DRM is very similar to AM HD Radio in that each station is broadcast via a channel 20 kilohertz wide (+/- 10 kHz ), and the radio is hand-tuned to each individual station's location on the dial.

Dozens of similar programs cropped up on AM radio stations all across the United States, from New England to Los Angeles, including the WWVA Jamboree in Wheeling, West Virginia ( 1933 ), the Renfro Valley Barn Dance in Kentucky ( 1939 ), the Louisiana Hayride ( 1948 ), the Tennessee Jamboree ( 1953 ) and Ozark Jubilee ( 1954 ).

* When WXKS ( AM ), formerly WKOX, went to conservative talk in 2010, it took a similar approach to the above " Rush Radio " stations in March 2010, previewing its own " Rush Radio " format with a collage of the shows they would present ( including Limbaugh ) along with patriotic speeches from American history.

Over the next two years, both stations aired similar formats and continued to simulcast from time to time, until the AM station split off on its own early in 1986 with an automated syndicated oldies format from Unistar as " K63 ", meeting with mild success.

Their co-owned AM station had earlier flipped to a similar hard rock format as KMZZ, initially airing the syndicated Z-Rock network for a time before briefly switching to a locally-based automated heavy metal format (" Mega Rock 980 ") and finally simulcasting 93X by 1993.

Molecules similar to Nod factors were isolated from AM fungi and were shown to induce MtEnod11, lateral root formation and enhance mycorrhization.

Shortly after the emergency lease had been approved by the Cambria County War Memorial, head coach Joe Selenski traveled to Canada to find the team uniforms and called War Memorial Marketing Director Dennis Grennell at 3: 00 AM to tell him that the only uniforms he could find were black and gold ( similar to the Bruins ' uniforms of the 1970s ), but he didn't have enough money to buy them.

Located at 560 on the AM dial, WFIL is immediately adjacent to New York City's WMCA ( at 570 ), and the two stations have similar histories: both were Top 40 stations in the 1960s, both underwent a format evolution as AM radio faded as a music medium, and both have a Christian / religious format today.

In September 1991, the AM launched a mostly automated beautiful music format known as " Wish ", a play on the old WWSH station which had a similar format in Philadelphia back in the 1970s.

A low-frequency message signal ( top ) may be carried by an AM or FM radio wave.

In other cases it may be desirable to maintain some degree of compatibility with older AM receivers, while still retaining the advantage of reduced transmission bandwidth.

More modest phased array longwire antenna systems may be employed by private radio enthusiasts to receive longwave, mediumwave ( AM ) and shortwave radio broadcasts from great distances.

Near-field effects of an AM antenna may extend out two miles ( 3 km ) or more.

In some forms of AM, the carrier may be removed, producing double sideband with suppressed carrier ( DSB-SC ).

Many areas of Lagos, such as Festac, contain many cyber cafés that serve scammers ; many cyber cafés seal their doors during afterhours, such as from 10: 30 PM to 7: 00 AM, so that scammers inside may work without fear of discovery.

It is preserved in the 13th century manuscripts Codex Regius and AM 748 I 4to but may have been originally composed in heathen times.

Frequencies, power levels and modes ( such as frequency modulation ( FM ), amplitude modulation ( AM ), and single-sideband modulation ( SSB ), often vary from country to country ; use of foreign equipment may be illegal.

AM is used mostly by broadcast services – other shortwave users may use a modified version of AM such as SSB or an AM-compatible version of SSB such as SSB with carrier reinserted.

These on-line stations will usually attract a small and loyal audience and may go unnoticed by the authorities, unlike the real AM / FM pirates who can easily be heard and traced on a conventional radio.

If a vacancy arises at another time, due to death or resignation, then it may be filled in one of two ways, depending of whether the vacancy is for a first-past-the-post constituency AM or for an additional-member AM.

FM stations may flip back and forth ( sometimes annoyingly rapidly when moving ) due to the capture effect, while AM stations ( including TV video ) may overlay or fade with each other.

They may use simple modulation schemes such as AM or FM, or more complex techniques such as digital coding, spread spectrum, and so on.

Some universities use the Latin degree names, and due to the flexibility of word order in Latin, Artium Magister ( AM ) or Scientiæ Magister ( SM ) may be used in some institutions.

Some engineers believe that CAM-D may be compatible with analog AM stereo with the right engineering.

On standard AM broadcast radios, the entire 9 kHz to 10 kHz allocated bandwidth of the AM signal may be used for audio.

Also the converter may not allow pass-through of the MW band, which is used for AM broadcasting.

Some digital radio systems provide in-band on-channel ( IBOC ) solutions that may coexist with or simulcast with analog AM or FM transmissions, while others are designed for designated radio frequency bands.

Use of air signal only radios ( AM / FM ) have declined in popularity with the rise of portable digital audio players, which allow users to carry and listen to the music of their choosing and may also include a radio tuner.

* Multiple modulation schemes: a few amateur HTs may allow modulation modes other than FM, including AM, SSB, and CW, and digital modes such as radioteletype or PSK31.
