Original Signal in a sentence

Principle of PAM: (1) original signal, (2) PAM signal, (a) amplitude of signal, (b) time Pulse-amplitude modulation (PAM), is a form of signal modulation where the message information is encoded in the amplitude of a series of signal pulses.

In this application there is a specific requirement that the harmonic content of the original signal be preserved without creating aliased harmonic content of the original signal above the original Nyquist limit of the signal (i.

Scrambling is accomplished by the addition of components to the original signal or the changing of some important component of the original signal in order to make extraction of the original signal difficult.

One way around this problem is to start with a low frequency signal of which the frequency can be precisely measured, and from this signal progressively synthesize higher frequency signals whose frequency can then be linked to the original signal.

As a result, an electronic backend ADC, that would have been too slow to capture the original signal, can now capture this slowed down signal.

Folded line spring reverberation main Delay /echo: Delay/echo units produce an echo effect by adding a duplicate instrument-to-amplifier electrical signal to the original signal at a slight time-delay.

Such reflections may cause signal attenuation and ghosting TV picture display; multiple reflections may cause the original signal to be followed by more than one echo.

Therefore, the power of the reflected signal is very low, several orders of magnitude less than the original signal.

When so-called high-side injection has been used, where the local oscillator is at a higher frequency than the received signal (as is common), then the frequency spectrum of the original signal will be reversed.

A brick-wall low-pass filter, H(f), removes the images, leaves the original spectrum, X(f), and recovers the original signal from its samples.

Additionally, it features the original signal box from Aughton Road station near Southport.

In these systems the original signal is first converted into digital form, and then the digital data is encrypted and sent.

Since the original signal is much more powerful, it can be detected many times further than twice the range of the sonar (as in the example).

Some audio formats feature a combination of a lossy format and a lossless correction which when combined reproduce the original signal; the correction can be stripped, leaving a smaller, lossily compressed, file.

Such images can be made while maintaining the full integrity of the original signal data, which is not modified in any way.

The advantage of this method of encryption is that none of the original signal is sent, only envelopes of the bandpass filters.

The Fourier transform is called the frequency domain representation of the original signal.

Then the function is represented by: :: As in the other proof, the existence of the Fourier transform of the original signal is assumed, so the proof does not say whether the sampling theorem extends to bandlimited stationary random processes.

The physical significance of this is that electromagnetic waves propagate down transmission lines and in general, there is a reflected component that interferes with the original signal.

The problem in the navigational case is that the receiver has to know when the original signal was sent.
