IF Amplifiers Flashcards
1
Q
What degree of selectivity is desirable in the IF circuitry of a wideband FM phone receiver?
A
15 kHz
2
Q
Which one of these filters can be used in micro-miniature electronic circuits?
A
Receiver SAW IF filter.
3
Q
A receiver selectivity of 2.4 kHz in the IF circuitry is optimum for what type of signals?
A
SSB voice.
4
Q
A receiver selectivity of 10 KHz in the IF circuitry is optimum for what type of signals?
A
Double-sideband AM.
5
Q
What is an undesirable effect of using too wide a filter bandwidth in the IF section of a receiver?
A
Undesired signals will reach the audio stage.
6
Q
How should the filter bandwidth of a receiver IF section compare with the bandwidth of a received signal?
A
Slightly greater than the received-signal bandwidth
