We analyze the accuracy of digital estimation of the signal spectrum.
Quantization noise
introduced by the analogtodigital converter (ADC) and fast Fourier transform (FFT) is allowed for. The basic analysis is carried out using the example of a test harmonic signal. The characteristic of the signaltonoise ratio, called the effective binary word size of a harmonic signal is introduced. Optimal combinations between the ADC word size and the FFT type used are discussed.
