No modulation was present at that instant. Fig. 4 shows a 1 kHz sine wave modulating the carrier 100% positive and negative. The positive parts are the top and bottom peaks. They are mirror images of ...
A novel full-wave rectifier turns an audio power amplifier into a simple modulator, that is then used to modulate an ...
We use a square wave for this test because it, like program material is considered a “complex” waveform (as compared to a simple sine wave). Also note the slight tilt in the square wave, which ...
In the hard-to-miss effects category are pedal effect circuits that have a sine wave injected into the supply voltage. To do just that, a common-source JFET amplifier was constructed in LTSpice ...
Jpk-pk=Jpk * 2 where: Jpk-pk = expected amplitude of a single sine-wave modulation in seconds TIA Measurements The TIA can directly measure PJ amplitude and frequency on both clock and data signals.
The use of time dithered pulse position modulation (TDPPM) instead of continuous sine waves eliminates potential signal cancellation because pulses, not continuous waves, are the transmission method.
Varying the sine wave’s amplitude achieves AM and pulse modulation. Varying the sine wave’s frequency or phase generates FM and ΦM, respectively.
As an example, a simple sine wave at 130Hz (C3) ring modulated with another sine wave at 390Hz, will output a signal with those original frequencies, plus new peaks at 260Hz (390-130) and 520Hz ...
