[Elecraft] "Another Better Mouse-trap?"

[William Carver]

"IMHO, the problem with most blankers, as mentioned below, is that the
designers don't introduce any delay in the signal path.  It takes some
time to amplify, detect and form the blanking pulses that drive the
noise gate.
Absent delay, the noise pulses get through the gate and do their
mischief before the blanking takes place."

That's right: the blanking pulse needs to open the gate before the
signal+noise pulse gets there. You can either delay the signal, or you
make the blanking pulse so quick that it naturally arrives there before
the signal. A wideband noise receiver can have less delay than the
receiver, and blanking pulses can be generated in nanoseconds with
todays fast circuits, so it can sometimes be done without a delay in the
signal path.
