- The relationship between the frequency and amplitude of the audio signal and the detected output waveform.
- The relationship between the AM envelope and the detected waveform.
- The causes and effects of diagonal clipping and rectifier distortion.
Homework Answers
the relationship between frequency and amplitude in AM is independent that is there is no relationship between them.
whereas in FM frequency of the output waveform frequency increases as the amplitude of baseband signal is increased that is directly proportional relationship.
2) the relationship between AM envelop and detected waveform is directly proportional.as the amplitude of the envelope is increasing more accurate output waveform will be present at the receiver,
3) basically diagonal clipping is associated with detection of AM signal. during the detection process if the capacitor is discharging quickly then some part of the baseband signal may be lost.
we will use diodes during the detection. distortion occurred in the diode is called as rectifier distortion.bassically it is due to minority carriers in the diode.

An information signal is of the form s(t) = sin(2*pi*t)/t. The signal amplitude modulates a carrier of frequency 10Hz. Find and sketch the Waveform and Fourier transform of the transmitted signal before and after AM modulation. For AM modulation you can consider the simple case of DSB format (or double-sideband suppressed carrier modulation).
