Some pulse modulation schemes also allow the narrowband analog signal to be transferred as a digital signal ( i. e. as a quantized discrete-time signal ) with a fixed bit rate, which can be transferred over an underlying digital transmission system, for example some line code.

A pulse ( physics ) | pulse traveling through a string with fixed endpoints as modeled by the wave equation.

Pulse dialing, dial pulse, or loop disconnect dialing, also called rotary or decadic dialling in the United Kingdom ( because up to 10 pulses are sent ), is pulsing in which a direct-current pulse train is produced by interrupting a steady signal according to a fixed or formatted code for each digit and at a standard pulse repetition rate.

Higher optical pulse output power, and better input sensitivity, combine directly to improve measuring range, and are usually fixed features of a particular instrument.

These ticks represent a fixed, regular aural pulse ; some metronomes also include synchronized visual motion ( e. g. pendulum-swing ).

A metronome only provides a fixed, rigid, relentless pulse ; therefore any metronome markings on sheet music cannot accurately communicate the pulse, swing, or groove of music: The pulse is often not regular ; e. g. in accelerando, rallentando ; or in musical expression as in phrasing ( rubato, etc.

Waves of different frequencies ( in light these are different colours ) can interfere to form a pulse if they have a fixed relative phase-relationship ( see Fourier transform ).

The duration of each pulse ( ranging from 0. 9 to 1. 2 seconds, with 0. 2 second blank intervals between each pulse ) differed in a fixed pattern, and repeated every ten seconds ; the 10-second pattern was common to all 8 stations and synchronized with the carrier phase angle, which itself was synchronized with the local master atomic clock.

Aircraft use DME to determine their distance from a land-based transponder by sending and receiving pulse pairs – two pulses of fixed duration and separation.

A multi-channel analyzer derives the gate pulse from a const-fraction discriminator and uses a fixed delay for a third copy of the original signal to account for the delay in the discriminator.

Nor does the AESA have any sort of fixed pulse repetition frequency, which can also be varied and thus hide any periodic brightening across the entire spectrum.

The intensity of the trapped pulse will decrease by a fixed percentage during each round trip within the cell due to both absorption and scattering by the medium within the cell and reflectivity losses.

That electronic frequency may be thought of as switched on and off to form the pulse train of an active sonar or radar system, and if the radar has a characteristic ( or known fixed ) PRR, can be used in Electronic Warfare as a measurable attribute that can be used to identify the type or class of a particular platform such as a ship or aircraft — in some cases, a particular unit.

A wazn is only used in musical genres with a fixed rhythmic-temporal organization including recurring measures, motifs, and meter or pulse.

Most of these motorized machines use a pulsatile or pulsating water pumping action at a relatively low, predetermined fixed pulse cyclic rate, designed to match the normal wave rate of healthy, unobstructed nasal cilia.

minimizing false negative errors for a fixed rate of false positive

For instance an arbitrageur would first buy a convertible bond, then sell fixed income securities or interest rate futures ( to hedge the interest rate exposure ) and buy some credit protection ( to hedge the risk of credit deterioration ).

It tried to keep a fixed exchange rate, and attempted to deal with inflation and sterling weakness by credit and exchange controls.

On 1 January 2008, the country entered the eurozone and adopted the euro as its official currency, replacing the Cypriot pound at an irrevocable fixed exchange rate of CYP 0. 585274 per EUR 1. 00.

Currencies can be classified as either floating currencies or fixed currencies based on their exchange rate regime.

In the latter case, exemplified by Bulgaria, Hong Kong and Latvia, the local currency is backed at a fixed rate by the central bank's holdings of a foreign currency.

Robert Mundell's " impossible trinity " is the most famous formulation of these limited powers, and postulates that it is impossible to target monetary policy ( broadly, interest rates ), the exchange rate ( through a fixed rate ) and maintain free capital movement.

* Marginal lending rate ( currently 1. 5 % in the Eurozone ) – a fixed rate for institutions to borrow money from the central bank.

; Goal independence: The central bank has the right to set its own policy goals, whether inflation targeting, control of the money supply, or maintaining a fixed exchange rate.

The euro did not begin circulating until 2002 but the exchange rate was fixed on 19 June 2000, with legal introduction of the euro taking place in January 2002.

The corporation could buy a forward rate agreement ( FRA ), which is a contract to pay a fixed rate of interest six months after purchases on a notional amount of money.

Scrip, a form of money meaningless outside the school, was created at a fixed exchange rate from a student's tuition.

So at a fixed value of g, the fractional rate of change of the clock-rate, the percentage change in the ticking at the top of an accelerating box vs at the bottom, is:

The arithmetic was actually implemented as subroutines, but with a one megahertz clock rate, the speed of floating point operations and fixed point was initially faster than many competing computers, and since it was only software, all the DEUCE's had it.

East Caribbean dollars ( EC $) per US $ 1 – 2. 7000 ( fixed rate since 1976 )

Interest rate changes often cannot keep up with hyperinflation or even high inflation, certainly with contractually fixed interest rates.

( For example, in the 1970s in the United Kingdom inflation reached 25 % per annum, yet interest rates did not rise above 15 % – and then only briefly – and many fixed interest rate loans existed ).

In interwar Germany, for example, much private and corporate debt was effectively wiped out ; certainly for those holding fixed interest rate loans.

Some performance fees include a " hurdle ", so that a fee is only paid on the fund's performance in excess of a benchmark rate ( e. g. LIBOR ) or a fixed percentage.

Because a nation's exchange rate has a big impact on its ' balance of trade ' and its ' balance of payments ' many economists favour freely floating exchange rates over the older, fixed ( or pegged ) rates of foreign currency exchange.

At the point of conversion, the rate was fixed at € 1 = 5. 94573 mk.

The SL-2 crew fixed one item during EVA by, reportedly, " hit it with hammer.

With the feet in a fixed position, the hammer is whirled about one's head and thrown for distance over the shoulder.

The band often used it live and the disk drives would stop working, prompting their keyboard player Gillian Gilbert to hit the sampler stand's leg with a lump hammer which fixed the problem!

Monkey and Odie make their one last attempt to get the car fixed, which still does not work until Odie simply taps the engine with a hammer.

This design was fixed in the 1924 Soviet Constitution :" The State Emblem of the USSR is composed of a sickle and a hammer on a globe depicted in the rays of the sun and framed by ears of wheat, with the inscription " proletariats of the world, unite!

Each hammer is connected by a rope to a fixed frame in the bell-ringing room.
