Dear Sir,

I am interested to download free, i. microwave and ii. Transmission lines and networks by Mr. Umesh Sinha. I am the professor in Electronics and communication branch of APS College of Engineering, Bangalore. I am referring your book for both subjects Transmission Lines and NW's & Microwave and Radar. This is for your kind information

Microwaves are a form of electromagnetic radiation with wavelengths ranging from one meter to one millimeter; with frequencies between 300 MHz (100 cm) and 300 GHz (0.1 cm).This comprehensive exploration of signals and systems develops continuous-time and discrete-time concepts/methods in parallel, highlighting the similarities and differences, and features introductory treatments of the applications of these basic methods in such areas as filtering, communication, sampling, discrete-time processing of continuous-time signals, and feedback. Relatively self-contained, the text assumes no prior experience with system analysis, convolution, Fourier analysis, or Laplace and z-transforms. This edition includes a companion book of MATLAB-based computer exercises for each topic in the text. Material on Fourier analysis has been reorganized significantly to provide an easier path for the student to master and appreciate the importance of this topic. Frequency-domain filtering is now introduced very early in the development to provide a central and concrete illustration of why this topic is important and to provide some intuition with a minimal amount of mathematical preliminaries.
