    Check what you remember

    Read the wording for your board, then hide it and explain Signal processing and noise reduction in your own words. Rough notes are fine. This is a self-check, with no mark or grade.

    Reference: AQA

    The machine must reject common-mode noise and have a high input impedance, with a time base and display producing a voltage–time trace.
