ABSTRACT:
A solid-state, signal conversion circuit for converting electrical, periodic analog signals to other analog signals of different amplitude and/or frequency and/or phase is disclosed. The input signal is demodulated, scaled and sampled and each sample converted, via an analog-to-digital (A/D) converter, to a digital word corresponding to the sample's amplitude. The digital words address a ROM which has other words stored at the addresses in correspondence with the desired values for a preselected output signal. Scaling means is used to keep the input signal to the A/D converter at a constant peak value regardless of fluctuations in the signal level. A comparator and subtractor are used to invert the downslope of input signals to avoid ambiguity problems when the output signal frequency is an even multiple of the input signal frequency.
