A Precision Amplitude-Distribution Amplifier
W. F. Caldwell, Granino A. Korn, Victor R. Latorre, G. Peterson · IRE Transactions on Electronic Computers · 1960
A new electronic slicer circuit produces output pulses whenever a random input voltage x(t) is between two slicing levels X - Δx/2 and X+Δx/2. The slicer pulses gate a counter to produce a direct digital readout count equal to the estimated first-order probability density of the input signal. The system was designed for random process studies with conventional electronic analog computers and has compatible accuracy.
