Because the pulse generator has a 2 ns pulse width
, the spectrum of the pulse generator has a 500 MHz bandwidth and 24 GHz centre frequency, as shown in Fig.
Simulated results indicate that 1) the susceptibility of CMOS RS flip-flops to microwave electromagnetic interference is inversely proportional to the frequency, 2) the interference power threshold is inversely proportional to the pulse width
and conversely the interference energy threshold is directly proportional to the pulse width
, 3) amplitude, frequency and pulse width
ought to be selected appropriately to bring about changes in the output state.
This does not limit the utility of the program to analyze other receiver designs, providing that the minimum RF pulse width
for signal processing is translated from time to clock cycles.
However, suppose the pulse width
is changed instead.
The delay required is chosen by evaluating the settling time of the RF input pulse and the minimum RF input pulse width
range desired for conversion.
The transmitted pulse width
is labeled "A" in the figure and the effective pulse width
after compression is labeled "B.
