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.
Findings verified that JamTech's technology exceeds measurements typically achieved by traditional analog pulse width
modulation (PWM) Class D amplifiers and delta-sigma PWM digital amplifiers for both absolute dynamic range and spectral noise floor, two important measures of fidelity in digital audio systems.
AUSTIN, Texas -- JamTech today announced the production availability of its game changing product, the JM2020 True Fidelity([R]) sub-ranging pulse width
modulation (PWM) digital audio amplifier.
This direct digital parallel conversion technique achieves high precision and fidelity by avoiding the non-linearity caused by pulse width
timing resolution limitations of silicon technology.
Until today, the pulsed IV measurement capability of R&D test systems has been limited to pulse widths
insufficient to prevent harmful thermal effects in many modern semiconductor devices.
PWCs: Two pulse width
counter modules provide advanced timer control, simplifying event duration measurement.
PWMs: The VRS51L2070 incorporates eight pulse width
modulators with up to 16-bit adjustable resolution.
