Basic Op Amp Circuits and Projects
This forms the fundamental principle behind many audio mixers, albeit less expensive units tend to employ operational amplifiers (op-amps). ... In its essence, a sample and hold circuit comprises a straightforward configuration, consisting of an electronic switch, a storage capacitor, and a high-input impedance voltage follower. ...
Application of Resonance Circuit
To avoid the problem of having several resonant circuits, modern receivers use a frequency mixer or heterodyne circuit, which always produces the same IF signal (445 kHz) but retains the audio frequencies carried on the incoming signal.
FET Audio Mixer Circuit
This FET audio mixer is an example of FET's versatility. FETs are originally designed for high frequency applications but they can be used for audio
Audio Filters: Designing an audio mixer
The microphone's audio will be amplified to line level by a pre-amplifier before it's combined with the smartphone's audio using an op-amp circuit. The combined audio will, then, be played on a speaker. So, for example, one will be able to mix vocals with an audio track when using this mixer.
Audio summing mixer- inverting or non inverting output?
All the audio mixer circuit examples I see online are based off of the summing amplifier: This is an inverting op amp configuration so the output is inverted. I built a similar circuit and I could...
