ABSTRACT:
Disclosed is a multichannel display device which is so constructed that the waveform of input signal of each channel displayed on the cathode ray tube may be enlarged or reduced in the horizontal sweep direction or the horizontal direction by setting a sampling time interval for sampling the input signal of the channel to store the same in a corresponding one of plural memory units provided for each channel, a reading time for reading a sampled data stored in the corresponding memory, and a horizontal sweeping speed or one-sweep time of a cathode ray tube for displaying the waveform of the input signal in accordance with the sampled data as read, so as to permit these three factors to have an interrelation determined with respect to the channel.
