Complementary infinite-impulse response (IIR) filter pairs can be synthesized to generate power-complementary, allpass complementary, or magnitude-complementary filter pairs (see, e.g., [1]). A very attractive alternative to generate a power-complementary low-pass/high-pass IIR filter pair is to use lattice wave digital (LWD) filters (parallel connections of two all-pass filters) [2]–[4]. Usual...

We study the combined and separate effects of three parts of finite multi-testtube cut and paste DNA computing. First, we reformulate the ideas of Csuhaj-Varjú, Kari, and Pǎun [1], Freund [3], and Priese, Rogojine and Margenstern [10] about multi-test-tube splicing DNA computing in terms of cutting and pasting as in Pixton’s work. Pixton shows [8, 9] that with finite cutting and pasting only re...

Quantization noise levels of two low-sensitive allpass filter structures, namely wave digital circulator filters (WDCF) and lossless digital integrator filters (LDIF), are compared. Allpass filters are of interest for design of lowpass and bandpass lattice filters. The results show, primarily, that second-order LDIFs have lower total quantization noise gains than corresponding WCDFs for any pol...

A current differencing transconductance amplifier (CDTA)-based multiple-input single-output (MISO) currentmode universal filter and a quadrature oscillator (QO) are presented in this paper. The same circuit is used in the filter and oscillator, which only consists of 2 CDTAs and 2 capacitors. The universal filter can realize low-pass, high-pass, band-pass, band-stop, and all-pass biquad filter ...
