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.
Claims4
A circuit comprising:
- a multi bit modulated squarer processor which calculates the square of a running average of an input signal by modulating the running average by a serial pulse density modulated bitstream representation of the input signal to obtain a multi bit representation of the input signal squared, and
- an integrator which integrates the square over the period of the input signal or a suitable time period to derive an integrated parallel binary representation of the mean square value of the input signal.
A circuit comprising:
- a multi-bit modulated squarer processor which calculates the square of a running multi-bit average of an input signal by modulating each bit of the multi-bit average with a single bit of a serial pulse density modulated bitstream representation of the input signal to obtain a multi-bit representation of the input signal squared;
- and
- an integrator which averages the square over a time period to derive an integrated parallel binary representation of the mean square value of the input signal.
