Abstract
A triangular to sine wave converters has a first multiplier having inputs connected in the form of a square multiplier and receiving a triangular-wave input; a direct current bias shifting a parabolic wave output of the first multiplier to a negative polarity; and a second multiplier having an input Y receiving a shifting output of the direct current bias, the second multiplier having an output X receiving the triangular-wave input, whereby the second multiplier produces a cubic-wave output approximate to a sine wave.
