This is the second half of our Transistor Circuits e-book. It contains a further 100 circuits, with many of them containing one or more Integrated Circuits (ICs).It's amazing what you can do with transistors but when Integrated Circuits came along, the whole field of electronics exploded.

今天，电视机与视讯转换盒应用中的大多数调谐器采用的都是传统单变换MOPLL概念。这种调谐器既能处理模拟电视讯号也能处理数字电视讯号，或是同时处理这两种电视讯号(即所谓的混合调谐器)。在设计这种调谐器时需考虑的关键因素包括低成本、低功耗、小尺寸以及对外部组件的选择。本文将介绍如何用英飞凌的MOPLL调谐芯片TUA603 ...

computes the eigenvalues of a symmetric tridiagonal * matrix T. The user may ask for all eigenvalues, all eigenvalues in the half-open interval (VL, VU], or the IL-th through IU-th eigenvalues.

The Rayleigh Integral Method is useful in computing the acoustic properties of a flat panel radiating into a half space.
