FFT Spectrum Analyzers use DSP techniques to provide in-depth waveform analysis with great flexibility (tutorial): https://bit. ly/2iaG3YZ.   Ian Poole in Radio-Electronics writes:A FFT or Fast Fourier Transform spectrum analyzer uses digital signal processing techniques to analyze a waveform using Fourier transforms to provide in depth analysis of signal waveform spectra. The FFT analyzer can provide information not available from swept frequency analyzers, enabling fast capture and forms o.......

Following on from my earlier blog : Let's Do Some Digital Signal Processing (Part 2) - One Pole Filter I thought it was about time that I took a look at Infinite Impulse Response (IIR) filters. IIR filters give much higher performance than Finite Impulse Response filters because they use feedback as well as feedforward in order to implement the filter response. This code shows how to implement an IIR biquad filter structure. #include #define COUNT 8 /* Number of samples to process */#d.......
