Vedclass · Answer

(A) In an $AM$ detector circuit,the capacitor $C$ discharges through the resistor $R$ during the interval between carrier peaks.To ensure the output voltage follows the envelope of the modulated signal,the time constant $RC$ must be significantly larger than the time period of the carrier wave $T_c$,but smaller than the time period of the modulating signal $T_m$.Mathematically,this is expressed as $T_c Since $T_c = 1/f_c$,the condition is $T_c << RC$.

For the output of an $AM$ detector circuit to follow the envelope of the carrier wave,which condition must be satisfied? ($T_c$ is the time period of the carrier wave.)
