The problem lies with the FFT operation. When operating in real time, each second I have access to only specific number of data (like 512 in this case). Filtering...

Hi Mr. Rick Lyons. My algorithm is for a bio-medical application (like an ECG). The algorithm processes the signal by first passing it through FIR filters. This...

I'm facing a problem with the implementation of the wavelet transform algorithm in real time. As of now processing capability isn't a bottleneck. Thanks!

I understood the point you're trying to make. Actually I thought roughly the same thing in the beginning. DTWT - Discrete Time Wavelet Transform - however when performed...

Real-time Wavelet Transform

Usually CIC filters are used in multi-rate DSP applications right? My filter is a gaussian FIR filter which has been developed by someone else.
