Dear Raghunathan,

as I wrote to you earlier in personal contact:

'The way you connected peak detector circuit should work. But I would
then increase discharging resistors from 1kOhm to about 10...22kOhm. The
reason for this is, that I thought only about a short reseting interval
of about some tens of miliseconds. If discharging transistors are
turned-on for a longer period, output current is a bit too high. It
should be limited to less than about 1mA.'

Bye,
Kai
