Abstract

PURPOSE: To establish the delay circuit which can cope with a number of ghosts, by providing the selection circuit between delay lines and taking either of the final output of delay line or the tap output of delay line to the input of the delay line of next stage.
CONSTITUTION: When the switch 33 is turned on, the selection circuit 17 sequentially selects the tap of the delay line 14 and stops after selecting the i-th tap when the switch 33 is turned off. In this case, the output is appeared at the terminal 36 and also is fed to the delay line 15 through the selection circuit 23. Next, selection is similarly made by turning on the switch 34. The output of the sum between the delay lines 14 and 15 is obtained for the output terminal 37. This circuit can obtain various types of delay outputs even with less number of analog switches.
