—This paper presents two-dimensional (2-D) VLSI digital filter structures possessing various symmetries in the filter magnitude response. For this purpose, four Type-1 and four Type-2 power-efficient and cost-effective 2-D magnitude symmetry filter architectures possessing diagonal, fourfold rotational, quadrantal, and octagonal symmetries with reduced(More)
By means of the delta operator, a new type of CNN, the (δ, c)-CNN, is introduced. It is a superclass of continuous-time (CT) and discrete-time (DT) CNNs with any saturation high gh-gain-, or hardlimiting sign-nonlinearity. It is shown that the (δ, c)-CNN allows continuous transition between different types of nonlinearities and between CT-and DT-CNNs,(More)
1. The muscarinic receptor subtype mediating contraction of the canine saphenous vein has been characterized using a range of muscarinic agonists and subtype-selective antagonists. 2. Oxotremorine M and (+)-cis-dioxolane behaved as full agonists, while in comparison L-660,863 ((+/-)-3-(3-amino-1,2,4-oxadiazole-5-yl)quinuclidine) acted as a partial agonist.(More)
