Question
Q2. Write either (T) for True or (F) for False on the followi
1. The free running frequency of the LM565 FM demodulator circuit is set internally.
2. For an FM carrier signal of frequency of 90 MHz, the local oscillator superheterodyne
receiver is set to 107 MHz.
3. For a carrier of 800 kHz, the output of the IF amplifier in AM receiver contains an image
frequency of 1600 kHz.
4. If the frequency band of the information signal extends to 10 kHz the upper limit of the
output spectrum of the IF amplifier in AM receiver is 465 kHz.
5.
The frequency range of the LM386 audio amplifier can extends to more than 15 kHz.
6. The voltage gain of the LM386 audio amplifier can be set to 120 dB by connecting a suitable
resistor and capacitor between pins 1 and 8.
