I HAVE BEEN WORKING ON A PROJECT FOR THE PAST THREE MONTHS WHICH IS "ECHO CIRCUIT". I HAVE AN IDEA AND I TRIED TO SEE IF I COULD USE FIVE JRC4558 IC, IN SERIES. BUT AT INTERVAL BETWEEN EACH OF THE ICS, THERE HAS TO BE A KIND OF DELAY. AT LEAST FIVE SECONDS IN DECENDING OTHERE. WITH THE OUTPUT OF EACH HALF (1\2) OF THE JRC CONECTED IN PARALLEL. THEN THE OUTPUT OF THE OTHER HALF, CONECTED TO THE INVERTING INPUT OF PIN ONE (1) OF EACH OF THE JRC'S.
THEN THE FINAL OUTPUT OF THE JRC4558 WHICH IS PIN SEVEN (7), IS CONECTED AS FEED BACK TO THE INITIAL OUTPUT OF THE FIRST JRC4558. AS THE ECHOING FEED BACK.
THANKS.....!!! PLEASE ANY CONTRIBUTION TO THIS PROJECT OF MINE WILL BE HIGHLY APPRECIATED.

With this method You can build a self-oscillating circuit. If You need this for audio signals (echo and reverb) try search on Google, few analog delay IC existiert for this purpose.
