Title:
TRANSMISSION OUTPUT CONTROL CIRCUIT
Document Type and Number:
Japanese Patent JPH04323915
Kind Code:
A
Abstract:

PURPOSE: To simplify a transmission output control circuit forming a burst transmission output in the time division multiplex communication system, to make an operation stable and to reduce a cost.

CONSTITUTION: This control circuit is provided with a rectangular wave basic control signal generator 1 generating a control signal to apply on/off control to a transmission output, a rectangular wave auxiliary signal generator 2 to bring the rising and falling characteristic of the control signal into a raised cosine waveform, an LPF 3 to waveform-shape its output, and the output and the control signal are added by an adder 4 and the sum as a switching control signal is given to a switch 5 to turn on/off the transmission output.
