This is necessary as the gas density in the tube is usually low, and most high energy gamma photons pass through undetected.

Analog and digital modulation facilitate frequency division multiplexing ( FDM ), where several low pass information signals are transferred simultaneously over the same shared physical medium, using separate passband channels ( several different carrier frequencies ).

# Map the codewords to attributes, for example amplitudes of the I and Q signals ( the equivalent low pass signal ), or frequency or phase values.

# Adapt pulse shaping or some other filtering to limit the bandwidth and form the spectrum of the equivalent low pass signal, typically using digital signal processing.

Carry out the modulation, for example by multiplying the sine and cosine waveform with the I and Q signals, resulting in the equivalent low pass signal being frequency shifted to the modulated passband signal or RF signal.

Some areas of the world such as Washington and Oregon in the United States, and Wales in the United Kingdom, have used geographic features to store large quantities of water in elevated reservoirs, using excess electricity at times of low demand to pump water up to the reservoirs, then letting the water pass through turbine generators to retrieve the energy when electrical demands peak.

To this end the glass is of a special low iron type that allows 90 % of the ultraviolet light in sunlight to pass.

AM demodulation requires the simple rectification of the RF signal ( so-called envelope detection ), and a simple RC low pass filter to remove remnants of the intermediate frequency.

In telecommunications in particular, it is often the case that those parts of the signal which are at low frequencies are " copied " up to higher frequencies for transmission purposes, since there are few communications media that will pass low frequencies without distortion.

ADM reduces slope error, at the expense of increasing quantizing error. This error can be reduced by using a low pass filter.

The final implementation replaced the integrator with a Predictor implemented with a two pole complex pair low pass filter designed to approximate the long term average speech spectrum.

As such, designing a filter consists of developing specifications appropriate to the problem ( for example, a second-order low pass filter with a specific cut-off frequency ), and then producing a transfer function which meets the specifications.

A digital filter will introduce noise to a signal during analog low pass filtering, analog to digital conversion, digital to analog conversion and may introduce digital noise due to quantization.

Introducing a digital filter requires considerable overhead circuitry, as previously discussed, including two low pass analog filters.

All systems are low pass to some extent.

Early in the match, Arsenal midfielder Robert Pirès played a low pass from the left flank to Bergkamp in the edge of the opponent area with his back to goal.

A low pass lifter is similar to a low pass filter in the frequency domain.

As the low and the warm front pass, the nimbostratus thins out into low stratus and the precipitation tapers off.

Classical analog filters are IIR filters, and classical filter theory centers on the determination of transfer functions given by low order rational functions, which can be synthesized using the same small number of reactive components.

* A low-pass filter passes low frequencies while blocking higher frequencies.

* A band-stop filter passes high and low frequencies outside of a specified band.

For instance, if all of the coefficients were equal to unity, a so-called boxcar function, then it would implement a low-pass filter with a low frequency gain of N + 1 and a frequency response given by the sinc function.

Fluids flow through a filter due to a difference in pressure — fluid flows from the high pressure side to the low pressure side of the filter, leaving some material behind.

# In this case, to better emulate the sound of a plucked string, we want the filter cutoff frequency to start in the mid-range and move low.

Buffer transfer by capillary action from a region of high water potential to a region of low water potential ( usually filter paper and paper tissues ) is then used to move the DNA from the gel on to the membrane ; ion exchange interactions bind the DNA to the membrane due to the negative charge of the DNA and positive charge of the membrane.

DC is often used where low hum is required but because of the high current at low voltage in the heater circuit, DC power was not viable until the advent of low cost solid state rectifiers and appropriate large capacitance filter capacitors.

In the measurement of loudness, for example, an A-weighting filter is commonly used to emphasize frequencies around 3 – 6 kHz where the human ear is most sensitive, while attenuating very high and very low frequencies to which the ear is insensitive.

# A high-pass filter ( green trace ) will distort the shape of a square wave by reducing its low frequency components.

It accomplishes this high combination of high-speed scalability with low latency by using huge filter tables based on the criteria designed by the network administrator.

* Treble-cut or low-pass filter, which attenuates high frequencies while passing low frequencies

The HPF and LPF sections for the series crossover are interchanged with respect to the parallel crossover since they appear in shunt with the low & high frequency drivers.

A low frequency signal with a similar instantaneous voltage characteristic first passes through the LPF, then the woofer, and appears at the lower Input terminal.

Central pontine myelinolysis presents most commonly as a complication of treatment of patients with profound, life-threatening hyponatremia ( low sodium ).

TNM usually presents as poor suckling and generalized hypotonia ( low muscle tone ).

Suda's list of fathers of Ibycus also presents problems: there were no historians in the early 6th century and Cerdas looks like an invention of the comic stage ( it has low associations ).

There, the HPF presents a low impedance to the signal, so the signal passes through the HPF, and appears at the lower Input terminal.

On the other hand a thick element presents less reactance at an off-resonant frequency, and consequently a Q as low as 5.

Any liquid with a low flash point presents a risk of fire or explosion if used in a kerosene wick lamp.

On the right side is the low relief Cardinal Consalvi presents to Pope Pius VII the five provinces restored to the Holy See ( 1824 ) made by the Danish sculptor Bertel Thorvaldsen.

Because the strait has such unusual tidal conditions, coupled with very low wave heights because of its sheltered position, it presents a unique and diverse benthic ecology.

With the East's low population density, however, this generally presents little problem.

The infection is acquired during sexual intercourse and presents with low back pain, penile discharge, low grade fever and an inability to pass urine.

When the breakdown voltage of the gap is reached, it then presents a low resistance to the circuit causing the C1 capacitor to discharge.

Further study suggests that the nanoscale topologies function not only due to the reduction of sites for macrofoulers to attach, but due to the same thermodynamic barrier that any surface with low wettability presents.

Conversely, a voltage follower inserted between a driving stage and a high load ( i. e. a low resistance ) presents an infinite resistance ( low load ) to the driving stage, an advantage in coupling a voltage signal to a large load.

A Winter Weather Advisory is issued by the National Weather Service of the United States when a low pressure system produces a combination of winter weather ( snow, freezing rain, or sleet ) that presents a hazard, but does not meet warning criteria.
