  1. Applications of Op-Amp Circuits Section 8.2

  2. Noise Cancellation Circuits

  3. Microphone is placed external to the headphone to detect noise.

  4. Circuitry Non-inverting amplifier phase-inverter Summer Speaker headset mounted microphone Music Source

  5. Non-Inverting Amplifier Av=1+R8/R6

  6. Phase-Inverting Amplifier Av=-R12/R10 A unity gain amplifier to cut-back on any audio distortion.

  7. Knobs Control over the magnitude of phase shifted signal. Thus, allowing users to fine-tune noise cancelling. Provides an option for turning on or off phase inverted signal
