Abstract
Circuitry is described for detecting a waveshape having a change of slope, such as the optical signal wave from a nuclear explosion. The wave is amplitude-sampled at a rate determined by a variable frequency clock pulse generator. Signal pulses indicative of the slope of the wave are generated from the amplitude samples, and a certain number of the most recently generated slope signals are stored in a shift register. Majority logic circuitry, connected to the shift register, generates an output signal when the majority of the slope signals in the shift register changes from a first slope majority to a second slope majority.
