This paper describes the hardware implementation of a digital spectrum analyzer which, by using a capture process of the signal under processing, performs some non parametric signal processing techniques. All the possibilities to implement a spectrum analyzer will arise to a bank filter analysis approach. When the instrument works as an off-line processor, the bank filter can be a linear transform, which results in a FFT as concerns with the analysis of the power density content of the data sample. Thus the FFT processor can be viewed as a set of equispaced filters with non-ideal cut-off and secondary lobes but optimum to analyze pure tones in a white noise environment.
