ABSTRACT:
A line noise signal measurement system is provided with detecting circuitry for providing a sensed analog signal. Compression circuitry is coupled to the detecting circuitry for providing an amplitude compressed signal responsive to the applied sensed signal. The compression circuitry has a stepwise substantially linear transfer function responsive to a variable magnitude of the applied sensed signal. Signal processing circuitry is coupled to the compression circuitry for sequentially generating a digital signal representative of the sensed analog signal. Digital processing circuitry sequentially identifies a maximum peak signal for a predetermined time interval and provides linearity correction for the identified maximum peak signals and generates a display of the corrected peak signals.
