What is emission F3F?

What type of emission is produced when a frequency modulated transmitter is modulated by a facsimile signal?

Two AM transmitting antennas are close together. As a result the two modulated signals are mixed in the final RF stage of both transmitters. What is the resultant effect on the other station?

The term used to refer to the reduction of receiver gain caused by the signal or a nearby station transmitter in the same frequency band?

What is the bandwidth occupied by the carrier, both sidebands and harmonics?

Noise is primarily

What is the type of interference that can be caused can when several repeaters are close together?

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
