TL;DR: In this paper, the authors provide a thorough treatment of the fundamental theorems and properties of discrete-time linear systems, filtering, sampling, and discrete time Fourier analysis.
Abstract: For senior/graduate-level courses in Discrete-Time Signal Processing. THE definitive, authoritative text on DSP -- ideal for those with an introductory-level knowledge of signals and systems. Written by prominent, DSP pioneers, it provides thorough treatment of the fundamental theorems and properties of discrete-time linear systems, filtering, sampling, and discrete-time Fourier Analysis. By focusing on the general and universal concepts in discrete-time signal processing, it remains vital and relevant to the new challenges arising in the field --without limiting itself to specific technologies with relatively short life spans.

TL;DR: In this article, the Fourier decomposition of continuous-time functions and discrete-time signals is compared, and the authors show that the process of sampling during discretization renders Fourier transformations of discrete time signals periodic, which places some important restrictions on analytical techniques as we shall see.
Abstract: A discrete function or discrete-time signal can be decomposed into a series of discrete sinusoids. An important difference between Fourier decompositions of continuous-time functions and discrete-time functions is that the process of sampling during discretization renders the Fourier transformations of discrete-time signals periodic. The repetition period of the Fourier function corresponds to the sampling frequency. This property of discrete-time Fourier conversions places some important restrictions on analytical techniques as we shall see.

TL;DR: In this article, a synthesis method for Chebyshev type II band-pass fllters in the microwave frequency range is presented, where substrate suspension, wavy edge coupling, ring resonators, defect ground structure (DGS), and a combination of the wavy-edge coupling and ring resonator may be used and were investigated to suppress the harmonic pass-band.
Abstract: In this paper, a synthesis method is presented for Chebyshev type II band-pass fllters in the microwave frequency range. We investigate the cause of the second harmonic passband of coupled-serial-shunted lines bandpass fllters. Filters are employed substrate suspension, wavy-edge coupling, ring resonators, defect ground structure (DGS), and a combination of the wavy-edge coupling and ring resonators may be used and were investigated to suppress the harmonic pass-band. With a combination of the wavy-edge coupled- lines and ring resonators, the harmonic pass-band of the parallel- coupled line fllter is rejected more efiectively. Several fllters are fabricated and measured to demonstrate the design.
