Figure shown the circuit diagram of a balanced modulator, the input applied to the top AM modulator is m (t), where as that applied to the lower AM modulator is – m (t); these two modulators have the same amplitude sensitivity. Show that the output s (t) of the balanced modulator consists of a DSB-SC modulated signal.
