Abstract :
A transformerless modulator-demodulator was described in a previous correspondence. Transistor switches were used at the inverting and noninverting inputs of an operational amplifier. This correspondence concerns improvements that may be realized by adding a second operational amplifier and moving the transistor switches to the inverting and noninverting outputs.
