Abstract
The invention herein provides a supervisory circuit which is adapted to monitor an input signal and produce as an output signal, a parametric signal corresponding to the input signal. The circuit includes an input for receiving the input signal, and a stochastic processor coupled to the input for receiving the input signal and processing it to derive a signal that represents a parametric measure of the input signal. An output connected to said stochastic processor provides the parametric output signal as an output for supervisory purposes.
Claims1
A running averager processor comprising:
- an (L bit) up down counter having incrementing and decrementing inputs, and an output;
- said counter being adapted to be incremented by a serial pulse density modulated bitstream, and decremented by said bitstream delayed by a (2L) shift register,
- whereby the output of said up down counter represents the running average of said bitstream.
