Designed and written by experienced and well-respected authors, this hands on, multi-media package provides a motivating introduction to fundamental concepts, specifically discrete-time systems. Unique features such as visual learning demonstrations, MATLAB laboratories and a bank of solved problems are just a few things that make this an essential learning tool for mastering fundamental concepts in today's electrical and computer engineering forum. Covers basic DSP concepts, integrated laboratory projects—related to music, sound and image processing. Other topics include new MATLAB functions for basic DSP operations, Sinusoids, Spectrum Representation, Sampling and Aliasing, FIR Filters, Frequency Response of FIR Filters, z-Transforms, IIR Filters, and Spectrum Analysis. Useful as a self-teaching tool for anyone eager to discover more about DSP applications, multi-media signals, and MATLAB.
Sample questions asked in the 1st edition of Signal Processing First:
Prove that the magnitude is an even function of and the phase is an odd function of for a conjugate-symmetric frequency response.
Consider the cascade of LTI systems shown in Fig. 4. (a) Determine h ( t ), the impulse response of the overall cascade system. (b) Determine y ( t ) when the input is u ( t ) (i.e., find the unit-step response of the overall system). Hint : Rearrange the systems to find an easy way. (c) Determine the output y ( t ) when the input is x ( t ) = u ( t ) – u ( t – 10). Exploit the LTI properties of the system.
Express each of the following in a simpler form: (a) ? ( t ? 10)*[ ? ( t + 10) + 2 e ? t u ( t ) + cos(100?)] (b) cos(100 ?t )[ ? ( t ) + ? ( t - .002)] (c) (d) Notes : Use properties of the impulse signal ? ( t ) and the unit-step signal u(t) to perform the simplifications. Be careful to distinguish between multiplication and convolution. Convolution is denoted by a 'star', as in x ( t )* ? ( t ? 2) = x ( t ? 2) and multiplication is usually indicated by juxtaposition as in x ( t ) ? ( t ? 2) = x (2) ? ( t ? 2).
