Abstract :
An architecture for real-time implementation of a system for time-frequency (TF) signal analysis and time-varying filtering is proposed. It is based on the S-method (SM) and its relationship with the Hartley transform (HT). Hardware design, for a fixed-point arithmetic, is well-structured and suitable for VLSI implementation. It is simpler than the system based on the short-time Fourier transform (STFT).
