(F)Element 3-45 IF Amplifiers Flashcards
What degree of selectivity is desirable in the IF circuitry of a wideband FM phone receiver?
15 kHz
Which one of these filters can be used in micro-miniature electronic circuits?
Receiver SAW IF filter
A receiver selectivity of 2.4 kHz in the IF circuitry is optimum for what type of signals?
SSB Voice
A receiver selectivity of 10 kHz in the IF circuitry is optimum for what type of signals?
double sided AM
What is undesirable effect of using too wide a filter bandwidth in the IF section of a receiver?
undesired signals will reach the audio stage
How should the filter bandwidth of a receiver IF section compare with the bandwidth of a received signal?
slightly greater than the received signal bandwidth
