ABSTRACT:
A summing amplifier which sums and amplifies two input signals and combines them in a single load or output device. It includes a bridge circuit using either 4 NPN or 4 PNP type transistors. Two transformers are used to achieve input relationship. A square wave of different frequency is applied to each of the two input terminals and the sum of the two input frequencies is converted to a three level waveform of constant amplitude but with on-time variations periodic at the difference frequency of the two input frequencies.
