"Bridging the distance among conception and alertness, this article covers all of the major components of recent DSP. ideas, functions, and implementation matters are offered, and a wealth of labored examples and finish of bankruptcy workouts give you the chance for self-learning. through the ebook emphasis is put on purposes to sign, snapshot, and video processing, and genuine time implementation of DSP algorithms utilizing DSP processors is highlighted." (from the again cover).
The textbook includes 14 chapters, prepared as follows:
• bankruptcy 1 introduces thoughts of DSP and provides a normal DSP block diagram. program examples are included.
• bankruptcy 2 covers the sampling theorem defined within the time area and frequency area and in addition covers sign reconstruction. a few functional concerns for designing analog antialiasing lowpass filters and anti-image lowpass filters are incorporated. The bankruptcy ends with a bit facing analog-to-digital conversion (ADC) and digital-to-analog conversion (DAC), in addition to sign quantization and encoding.
• bankruptcy three introduces electronic signs, linear time-invariant approach suggestions, distinction equations, and electronic convolutions.
• bankruptcy four introduces the discrete Fourier rework (DFT) and electronic sign spectral calculations utilizing the DFT. equipment for using the DFT to estimate the spectra of assorted indications, together with speech, seismic indications, electrocardiography info, and vibration signs, are established. The bankruptcy ends with a piece devoted to illustrating quickly Fourier remodel (FFT) algorithms.
• bankruptcy five is dedicated to the z-transform and distinction equations.
• bankruptcy 6 covers electronic filtering utilizing distinction equations, move capabilities, method balance, electronic filter out frequency responses, and implementation equipment akin to direct-form I and directform II.
• bankruptcy 7 bargains with numerous tools of finite impulse reaction (FIR) filter out layout, together with the Fourier remodel technique for calculating FIR filter out coefficients, window technique, frequency sampling layout, and optimum layout. bankruptcy 7 additionally comprises functions that use FIR filters for noise aid and electronic crossover method design.
• bankruptcy eight covers numerous equipment of limitless impulse reaction (IIR) filter out layout, together with the bilinear transformation (BLT) layout, impulse-invariant layout, and pole-zero placement layout. functions utilizing IIR filters comprise audio equalizer layout, biomedical sign enhancement, dual-tone multifrequency (DTMF) tone iteration, and detection with the Goertzel algorithm.
• bankruptcy nine introduces DSP architectures, software program and undefined, and fixed-point and floating-point implementations of electronic filters.
• bankruptcy 10 covers adaptive filters with functions comparable to noise cancellation, approach modeling, line enhancement, cancellation of periodic interferences, echo cancellation, and 60-Hz interference cancellation in biomedical signals.
• bankruptcy eleven is dedicated to speech quantization and compression, together with pulse code modulation (PCM) coding, mu-law compression, adaptive differential pulse code modulation (ADPCM) coding, windowed changed discrete cosine rework (W-MDCT) coding, and MPEG audio layout, in particular MP3 (MPEG-1, layer 3).
• bankruptcy 12 covers issues relating multirate DSP and functions, in addition to rules of oversampling ADC, resembling sigma-delta modulation. Undersampling for bandpass indications can be examined.
• bankruptcy thirteen introduces a subband coding method and its implementation. ideal reconstruction stipulations for a two-band process are derived. Subband coding with an software of knowledge compression is tested. moreover, the bankruptcy covers the discrete wavelet remodel (DWT) with purposes to sign coding and denoising.
• ultimately, bankruptcy 14 covers snapshot enhancement utilizing histogram equalization and filtering equipment, together with side detection. The bankruptcy additionally explores pseudo-color snapshot iteration and detection, two-dimensional spectra, JPEG compression utilizing DCT, picture coding utilizing the DWT, and the blending of 2 pictures to create a video series. eventually, movement reimbursement of the video series is explored, that's a key component of video compression utilized in MPEG.
