A diode detector is used to detect an amplitude modulated wave of 
modulation by using a condenser of capacity 250 picofarad in parallel with a load resistance 100 kilo ohm. Find the maximum modulated frequency which could be detected by it .
Text Solution
Verified by ExpertsB
Given: Resistance 
kilo ohm 
Capacitance 
picofarad 
The higher frequency which can be detected with tolerable distortion is
This condition is obtained by applying the condition that rate of decay of capacitor voltage must be equal or less then the rate of decay modulated singnal voltage for proper detection of mdoulated signal.
