Abstract :
A single-sideband (SSB) frequency converter using only exclusive-or logic gates and no reactive or frequency-selective analog circuit elements takes square-wave inputs at two arbitrary frequencies f1and f2and generates an output waveform whose principal spectral component is at either f1+f2or f1-f2, selectably. A pair of outputs is generated in phase quadrature.
