Communications

It is defined as the output power when the RF amplifier response is 1-dB less than the ideal linear gain response

The predominant cause of phase distortion

It is the total phase shift encountered by a signal and can generally be tolerated as long as all frequencies undergo the same amount of phase delay

________ occurs when different frequencies undergo different phase shifts and may have detrimental effect on the complex waveform

_________ occurs when the amplitude-versus-frequency characteristics of a signal at the output of a receiver differ from those in the original information signal

It is the result of non-uniform gain in amplifiers and filters

It is the result of harmonic and intermodulation distortion and is caused by non-linear amplification

It is a parameter associated with the frequencies that fall within the passband of the filter

It is generally defined as the ratio of the power transferred to a load with a filter in the circuit to the power transferred to a load without a filter

It is an indication of the reduction of the S/N ratio as a signal propagates through the receiver.

The law that states that the wider the bandwidth and the longer the time of transmission, the more information that can be conveyed through the system

Also known as black-body noise

Also known as deep-space noise

Man-made noise occurs randomly at frequencies up to around

Space noise contains less energy below

Its operation involves an exchange of energy between kinetic and potential

It is a function of component aging and changes in the ambient temperature and humidity

Which of the ff crystals is commonly used in microphones?

Which of the ff crystals is often used for frequency control in oscillators?

It is an oscillator circuit that generates well-defined, stable waveforms that can be externally modulated or swept over a given frequency range
