Multichannel display device
First Claim
1. A multiple display device comprising:
- means for sampling multichannel input signals;
a memory having a plurality of memory units for storing sampled data received from said sampling means, the number of said memory units being the same as that of the number of channels;
means for writing the sampled data into said memory units at common sampling time intervals;
data readout means for reading out sampled data from said memory units at readout time intervals identical with said common sampling time intervals;
display means for displaying the waveforms of said input signals;
a horizontal sweep signal generator for producing and supplying to said display means a horizontal sweep signal whose frequency is varied in accordance with each respective multichannel signal; and
channel switching means for simultaneously displaying said input signals means.

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.
