Title:
WAVEFORM SHAPING DEVICE
Document Type and Number:
Japanese Patent JP3154541
Kind Code:
B2
Abstract:
PURPOSE: To provide a waveform shaping circuit for shaping the waveform of G signals so that collisions can be recognized at early stages.
CONSTITUTION: G signals are sampled by a sampling circuit 11 at intervals of TH hours. The sampled values are held in a D(t-TH) holding circuit 13, a D(t) holding circuit 14 and a D (t+TH) holding circuit 15. An adder 16 computes {D(t)-D(t-TH)} and an adder 17 computes {D(t)-D(t+TH)}. When these computed values are larger than predetermined values αG, βG, respectively, a comparator 18, 19 outputs a signal of H-level and outputs a D(t) signal via a gate 23; that is, it outputs a peak value. When the peak value cannot be detected, a G signal delayed by TH hours by a TH delay circuit 25 is output via a gate 24. As a result, when G signals are integrated after waveform shaping, their increase is sharper than that of the actual G signals.
