I stumble a bit on the following design problem. Should be easy for you
folks!!
I have a signal coming from one half of a 4538A monostable that generates
15uS pulses at 30uS interval. From this, I want to generate a second pulse
which starts at the _end_ of a 15uS pulse and ends only at the _beginning_
of the next 15uS pulse.
However, sometimes the next 15uS pulse can be delayed by as much as 5mS,
in that case the second pulse should also last that long, that is, until
the beginning of the next 15uS pulse.
Note that the other half of the 4538 is free to use.
Any suggestions or ideas to put me on the right track are welcome.
Fred
I knew I forgot a important detail :(
The second pulse MUST be triggered by the transition at the end of a 15uS
pulse.
