Circuit for formation of mean value of input signal - has reversible counter, oscillator and D:A convertor

摘要

The reversible counter counts the pulses which emanate from oscillator. The D/A convertor digital input is connected to the counter digital output, and its analogue output is connected to the circuit signal output. A comparator has its inputs connected to the signal input and output, and its output is connected to the counter reversing input in order to match output signal to the input signal.
