Abstract:
A device for signal processing, comprising:means for receiving a time varying input signal having a waveform;a switched capacitor storage array for short-term storage of said input signal waveform;means to switch between writing locations comprising individual capacitors of said storage array for the purpose of writing discrete values of said input signal waveform into said individual capacitors of said storage array, wherein said discrete values correspond to values of said input signal waveform at discrete time steps;advancing means, interfacing with said switching means, said advancing means functioning to increment a storage address of said individual capacitors from one to each subsequent one in a repeatable order, and said advancing means being incremented by a circuit control signal;means to switch between said individual capacitors of said storage array for the purpose of reading discrete values of said input signal waveform stored therein, said individual capacitors being located at an offset from said writing locations, wherein said offset between writing and reading locations comprises a time delay from a writing operation; andmeans to output a signal in correspondence with said input signal, but having discrete waveform values corresponding to said input signal at discrete time steps and exhibiting a time delay from said input signal.
