In this study, we present an efficient Haar discrete wavelet transform architecture using
Radix-2^ r 2 r multiplier and 4: 2 compressor. The functionality of this architecture is verified …

Non-local mean (NLM) adaptive filtering is a well-explored technique for the denoising of
images and electrocardiogram signals. In NLM filtering, the signal value at a particular …

Keyword spotting (KWS) is the task of detecting some specific words of interest in a text or
speech signal. The intention or context of a conversation posted on different social platforms …

Zero frequency filtering (ZFF) is a well-explored technique for detecting glottal closure
instants (GCIs) from the speech signal. The features extracted from the ZFF of the speech …

The prominent formants are observed in the short-term magnitude spectra (ST-MS) of
vowels. Consequently, the variance of the ST-MS is relatively more for the vowels than other …
