Signal generation duties could easily be handled by a 555 circuit at the low end, and a computer sound card at the higher end. [brmarcum] obviously put some time into his tutorial, but it’s not ...

Figure 1 Slope detection method where a bandpass slope below the resonant peak is used to create a slope-induced amplitude modulation where a simple envelope detector can be used to recover the ...

There are many ways to build a radio receiver, but most have a few things in common, such as oscillators, tuned circuits, detectors, mixers, and amplifiers. Put those together in the right order an… ...

Abstract: The reversal of the current directions in audio circuit elements causes polarity inversion of the acquired audio signal with respect to the reference input signal. The objective of the work ...
