In this paper the asymptotic limits of negative group delay (NGD) phenomena in multi-stage
RLC resonator-based circuits are discussed. A NGD-bandwidth-product limit is derived as a …

Constrained least-squares design and constrained Chebyshev design of one-and two-
dimensional nonlinear-phase FIR filters with prescribed phase error are considered in this …

A computationally efficient, low-power (107.6 μW@ 1.1 V), small core area (2.82 mm 2@
0.35 μm), 16-band nonuniformly spaced digital filter bank with stop-band attenuation of more …

We present a unified approach to the design of two well-known classes of computationally
efficient digital filters, namely the interpolated and frequency-response-masking (FRM) FIR …

In this paper, we propose a novel algorithm for sparse finite impulse response (FIR) filter
designs. The objective of the sparse digital filter design problem considered in this paper is …

Frequency response masking (FRM) technique along with the Canonic Signed Digit (CSD)
representation is a good alternative for the design of a computationally efficient, sharp …

Hilbert transformers and half-band filters are two very important special classes of finite-
impulse response filters often used in signal processing applications. Furthermore, there …

Frequency translation of audio signals requires the use of very sharp Hilbert transformer if
the low frequency components are to be faithfully translated. Unfortunately, the order of a …

Digital filter banks are extensively used in an SDR channelizer for channelization. The
objective of this research work is to design a low computational complexity FIR filter bank for …

In this paper, a novel recursive realization method with word length reduced is proposed to
synthesize linear-phase FIR filters for arbitrary bandwidth. By exploring the sparsity in the …
