DSP Sample Calculations.pdf

The files in this directory present sample calculations to supplement

the material in chapter 15, "DSP and Software Radios". The .mcd files

were generated with Mathcad 7 and the .pdf files are Adobe Acrobat

versions of those files.

exp_decay.mcd exp_decay.pdf

Compares the exponential decay generated by a digital and an analog

circuit.

fourier_conv.mcd fourier_conv.pdf

Demonstrates how to convolve sine waves with a signal to determine

its frequency content. This is the same basic method used by the

Fourier transform.

quant_rand.mcd quant_rand.pdf

Quantizing a random signal results in quantization noise.

quant_sine.mcd quant_sine.pdf

Quantizing a periodic signal results in quantization spurs. The

spurs can be reduced by dithering.

sampling.mcd sampling.pdf

Sampling in the time domain results in periodicity in the frequency

domain (alias frequencies).

sinc.mcd sinc.pdf

Linear and dB plots of the sinc function.

sine_aprox.mcd sine_aprox.pdf

Generating a sine wave using a fifth-order curve fit.

windowing.mcd windowing.pdf

Demonstration of the windowing method of calculating FIR filter

coefficients.
