https://doi.org/10.1007/978-3-642-67660-4phase FIR filters will be presented. Finally, there will be a discussion of the effects of finite precision arithmetic on the filter performance and the major applications for FIR filters will be outlined.

Signal representation and system response,ng of the electrical signal, most people would be able to identify the instrument being played, i.e. would be able to distinguish between a guitar and a piano. Some people might be able to identify the pitch and hence the note being played.

The fast Fourier transform, The chapter thus develops the simplified decimation-in-time fast Fourier transform (FFT) algorithm which makes for much easier computation of the transformed values. The FFT is widely applied in the practical implementation of large-. DFT processors.

Adaptive filters,nal exists within a narrow bandwidth of . Hz centred at a frequency . Hz and is subjected to additive noise or interference whose power is spread over a much wider band of frequencies. The quality of the signal, or more precisely the signal-to-noise ratio can be improved by application of a filter of bandwidth . Hz centred at . Hz.

The Fourier transform and spectral analysis,the power spectrum from signal sample data records. The power spectral density of a signal was defined previously in section 7.3 via the autocorrelation sequence. Here we extend this to the case of a discretely sampled sequence, .(.) which, in most practical situations, is restricted to a finite and limited number of signal samples.
