If we replace the potentiometer VR1 with an AC signal plus DC bias signal in any of the previous Figures 3 to 17, the voltage controlled attenuators can become an amplitude modulator circuit instead.
The average textbook definition of modulation reads: modulation is a process in which the frequency, phase or amplitude of a carrier wave varies in step with the instantaneous value of the modulating ...
Pinpointing the minimum and maximum transient noise bandwidth for a transient noise simulation is a non-trivial task. But ...
The key parameters of the FSS technique and their impact on EMI performance. How to evaluate FSS performance using simulation, ICs, and a signal generator. Frequency spread spectrum (FSS) is a ...
Synchronous Detection is a useful technique for extracting low level signals buried below the noise floor, with many instrumentation applications. Some examples include measuring very small resistance ...
