Abstract

PURPOSE:To avoide the malfunction of the terminal side due to unstable waveform at the switching of electronic switch, by connecting a high resistance between the input and output of the electronic switch, in the transmission waveform generating circuit which connects high frequency signal with low frequency signal by turning on one of the two electronic switches and turning off another. CONSTITUTION:The electronic switch 3 is turned on and the electronic switch 4 is turned off with the signal from the microprocessor A. The clock signal is given from the processor A to the shift register B and the control signal is stored in the register B, and when the work is finished, the switch 4 and the electronic switch 2 are turned on and data is output to the terminal side driver D with the clock from oscillator E. The output pulse is counted with the counter and when it is judged that the data signal in the register B is completely output, the switches 2 and 4 are turned off and the switch 1 is turned on. Further, the waveform of the reception signal band is output from the processor A.
