Received Signal in a sentence

By contrast, in narrowband systems where the signal bandwidth is low, the received signal quality will be severely lowered if the jamming power happens to be concentrated on the signal bandwidth.

Although "Doppler" has become synonymous with "velocity measurement" in medical imaging, in many cases it is not the frequency shift (Doppler shift) of the received signal that is measured, but the phase shift (when the received signal arrives).

Such a receiver multiplies the received signal separately with both a cosine and sine signal to produce the received estimates of and respectively.

Additionally, the various paths often distort the amplitude and/or phase of the signal, thereby causing further interference with the received signal.

Below is a table summarizing useful cases: main The signal intensity (power per unit area) can be converted to received signal power by multiplying by the square of the wavelength and dividing by 4π (see Free-space path loss ).

Furthermore, typical problems with signal transmission (such as differing received signal levels between different colors) would produce unpleasant side effects.

Ideally a filter would have a high attenuation to adjacent channels, but maintain a flat response across the desired signal spectrum in order to retain the quality of the received signal.

In air navigation or radio frequency identification, a flight transponder is a device that emits an identifying signal in response to an interrogating received signal.

It determines whether a receiver can lock on to the carrier and if the information encoded in the signal can be retrieved, given the amount of noise present in the received signal.

Multipath waves combine at the receiver antenna, resulting in a received signal that may vary widely, depending on the distribution of the intensity and relative propagation time of the waves and bandwidth of the transmitted signal.

When done properly this produces a received signal which more closely resembles the original or desired signal, allowing the use of higher frequencies or producing fewer bit errors.

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.

Thus, each received symbol is demodulated to one of the points in the constellation and a comparator then computes the difference in phase between this received signal and the preceding one.

Thus, the received signal will be expressed by : where is the number of received impulses (equivalent to the number of electromagnetic paths, and possibly very large), is the time delay of the generic impulse, and represent the complex amplitude (i.

Some electoral officers told NAN that they commenced voting “at the time we received signal from our Chief Security Officer (CSO) to start”.

Onyema said the exercise would continue as soon as the airline received signal from the Nigerian High Commission.

If a received signal is too strong a temporary fix is to wrap the cable around a pencil until the desired level of attenuation is achieved.

In a communications satellite, a transponder gathers signals over a range of uplink frequencies and re-transmits them on a different set of downlink frequencies to receivers on Earth, often without changing the content of the received signal or signals.

In the echo cancellation (ECH) scheme, the transmitter locally simulates the echo it expects to receive, and subtracts it from the received signal.

In this system, the demodulator determines the changes in the phase of the received signal rather than the phase (relative to a reference wave) itself.
