Q1:

A diode detector load consists of 0.01 μF capacitor in parallel with a 5 k ohms resistor. The maximum depth of modulation without diagonal clipping at modulating frequency of 1000 Hz and 10 kHz is

A 0.76, 0.24

B 0.95, 0.3

C 0.24, 0.76

D 0.3, 0.95

ANS:B - 0.95, 0.3

At f = 1 KHz Similarly for 10 kHz,
