this is probably a simple one for anyone with some electronics design experience (which I do not have). Can anyone tell me how to build a simple circuit which generates a square wave but has every nth pulse suppressed? So, to put some (example) numbers to it, the wave form could be described as such: Three 1 µs-wide positive pulses at 5 ms intervals (i.e. 200 Hz) every 20 ms. So, this example indicates that every 4th pulse should be suppressed.
Thanks much in advance!
