Homomorphous system for non-linear processing of analog signals

摘要

For the purpose of simpler integratability, homomorphous systems for non-linear processing operations on analog signals (Vi, Vi1, i = 1, 2, ..., n) are realised by switch-capacitor networks in which exponential voltage characteristics are used on logarithmic capacitances and on a delogarithmic capacitance to give logarithmic voltage/pulse width transformations or to give an exponential pulse width/voltage transformation.
