BALANCED MODULATOR

Balanced modulator is a type of modulator which is used for generation of DSB-SC waves.In balanced modulator two AM modulators are used. Same message signal with 180° phase shifting is given to each modulator {m(t) for modulator1 and -m(t) for modulator2 }. Due to this carrier current will cancel each other. If both modulators are perfectly balanced the carrier current will perfectly cancelled.
