Abstract
A dual trace display device having a gate circuit for receiving input signals, a sweep signal generator, a rectangular waveform generator supplied with the output signal from the sweep signal generator, and a driving circuit supplied with the output signal from the rectangular waveform generator and controlling the gate circuit. In this case, a display device is supplied with the output signals from the gate circuit and the sweep signal generator for displaying the same thereon.
Claims5
A dual trace display device comprising:
- a. two input terminals supplied with two signals to be displayed, respectively,
- b. a gate circuit connected to receive said two input signals,
- c. a sweep signal generator producing a signal in synchronism with one of said two input signals,
- d. a rectangular waveform generator connected to receive the output from said sweep signal generator and producing an output signal,
- e. a driving circuit connected to receive the output from said rectangular waveform generator, producing a pair of signals with opposite polarities and applying said signals to said gate circuit to alternatively pass said two input signals through said gate circuit, and
- f. a display device connected to receive the outputs from said gate circuit and said sweep signal generator and display thereon said input signals with the same reference axis and simultaneously in a time sequential manner.
