摘要：This specification discloses a high-speed pulse delaying circuit having itsextremely slight minimal delay and adapted for use as a time-base circuit for a widebandoscilloscope. The pulse delay circuit comprises essentially an integrator consisting of aresistor, a capacitor and a grounded resistor connected to the capacitor in series and ahigh-speed pulse generator using an avalanche transistor. The grounded resistor hassuch a low resistance that the waveform of the integrator output resulting from theintegration of a rectangular input pulse has a sharp rising portion at a positioncorresponding to the leading edge of the rectangular pulse, thereby to reduce theminimal delay time. Provision of a voltage adjustment circuit is made for varying theemitter potential of the avalanche transistor to vary the delay time.
