7.
In the TV receivers, the device used for tuning the receiver to the incoming signal is

8.
The modulation technique that uses the minimum channel bandwidth and transmitted power is

9.
Calculate the bandwidth occupied by a DSB signal when the modulating frequency lies in the range from 100 Hz to 10KHz.

10.
In Amplitude Demodulation, the condition which the load resistor R must satisfy to discharge capacitor C slowly between the positive peaks of the carrier wave so that the capacitor voltage will not discharge at the maximum rate of change of the modulating wave (W is message bandwidth and ω is carrier frequency, in rad/sec) is
