Efficient VLSI Architecture for Decimation-in-Time Fast Fourier Transform of Real-Valued Data

Abstract: The decimation-in-time (DIT) fast Fourier transform (FFT) very often has advantage over the decimation-in-frequency (DIF) FFT for most real-valued applications, like speech/image/video ...

Comb-Based Decimation Filters for

Abstract: This paper proposes several novel decimation filtering schemes tailored to the design of SigmaDelta analog-to-digital (A/D) converters. On the one hand, it extends the class of modified-sinc ...
