01 / The question
Does the circuit sound the way its response predicts?
This laboratory project examined an audio PCB with physiological tone correction and volume control.
02 / The intuition
A mechanism worth testing.
Use frequency response and saturation behaviour to connect circuit functions to their operating limits.
03 / The work
Inside the method.
Explore each part of the approach.
01Analyse the circuit
The work identified the roles of analogue stages and controls.
02Measure the response
Bode measurements examined gain and frequency dependence.
03Test operating limits
Signal-level tests explored saturation and practical behaviour.
04 / The observations
What emerged.
The notes document characterisation of the PCB and its controls, rather than a claim of independently designing an entire audio product.
This account is based on recorded project notes. Original reports, figures and datasets are not embedded here.
05 / The limits
Where the evidence stops.
Original schematics and measured response curves are needed to publish precise gains, bandwidths or distortion limits.
