Abstract :
A waveform fitting algorithm is used to measure the frequency response of a linear impedance. This method is capable of determining the harmonic amplitudes of a triangular signal up to the 50th harmonic. Amplitudes 80dB below the fundamental can be measured by using a 16-bit analogue to digital converter (ADC)
