Q15.30Multiple choice
An audio signal is modulated by a carrier wave of 20MHz such that the bandwidth required for modulation is 3kHz. Could this wave be demodulated by a diode detector which has the values of R and C as
- (i)R = 1 kΩ, C = 0.01µF.
- (ii)R = 10 kΩ, C = 0.01µF.
- (iii)R = 10 kΩ, C = 0.1µF.
