Implement a speech compression technique known as Linear Prediction Coding (LPC) using DSP System Toolbox™ functionality available at the MATLAB® command line.
Showcases a block that outputs the streaming power spectrum estimate of a time-domain input via Welch's method of averaged modified periodograms.
Estimate the group delay of a filter in Simulink. Group delay is defined as -d(phi(f))/d(f). To estimate the group delay of the filter extract the phase response and compute its negative
Perform high resolution spectral analysis by using an efficient polyphase filter bank sometimes referred to as a channelizer.
Perform high resolution spectral analysis by using an efficient filter bank sometimes referred to as a channelizer. For comparison purposes, a traditional averaged modified periodogram
Showcases zoom FFT, which is a signal processing technique used to analyze a portion of a spectrum at high resolution. DSP System Toolbox offers this functionality in MATLAB through the
Use the Discrete Transfer Function Estimator block to estimate the magnitude and phase response of a continuous-time analog filter.
The Zoom FFT block implements zoom FFT based on the multirate multistage bandpass filter designed in Complex Bandpass Filter Design. If you specify the center frequency and the decimation
Programmatically obtain the latency of an FFT HDL Optimized block in a model. You can use the latency value for delay matching of parallel data paths.
When you want to transform frequency-domain data into the time domain, use the IFFT block.
