Circuit for stochastic ergodic multiplication - has reference signals originated from same oscillator with frequency dividers

摘要

The circuit to multiply stochastic ergodic parameters uses a common oscillator (OSC) with parallel connections to two frequency dividers (FT1,FT2). Each of these is in series with a reference signal source (SG1,SG2) which forms a saw-tooth waveform output from a rectangular pulse waveform input. The saw-tooth waveform signals pass forward to converters (KV1, KV2), each fed with a binary or analogue input signal (e1,e2) proportional to the experimental value component which requires multiplication. Outputs from the converters continue to an AND gate (U) which sums the integrated values, so that the output from the AND gate is proportional to the product (e1,e2) of the input signal values.
