For introductory courses (sophomore/junior) in Digital Signal Processing and Signals and Systems. Text may be used before the student has taken a course in circuits. This text is derived from DSP A Multimedia Approach, published in 1997, which filled an emerging need for a new entry-level course not centered on analog circuits in the ECE curriculum. It was also successfully used in 80 universities as a core text for linear systems and beginning signal processing courses. This derivative product, Signal Processing First [SPF] contains similar content and presentation style, but focuses on analog signal processing. DSP A Multimedia Approach remains in print for those who choose a digital emphasis for their introductory course.
Good intro DSP book, presenting everything at a good pace. Also nice for those who want a bit of review. Might be a bit too introductory at times though.
As an introductory DSP text, DSP First covers quite a bit of ground: 1)a review of complex number manipulation and phasor representation 2)common concerns with sampling, aliasing, and hardware implementation 3)the important concepts of linearity and time invariance 4)Fourier and FFT 5)signals & systems review (convolution, cascading, impulse response, step function, impulse signal, cascading) 6)comparisons of signals/systems in the time domain, frequency domain, and z-domain 7)and all manner of filters (FIR, bandpass, feedback, feed forward, etc.)
Because I read a preliminary edition of the text, there were math, figure misidentification, or typographical errors in various places, but overall the text was still understandable in most cases. The largest drawbacks of this particular version of the text were a lack of an index or problem set answers. I'm not sure if those improvements have been made in subsequent printings, but I would hope so.
