From the reviews: "In the book ... Wei and Zhang have selected and presented the analysis of square, triangular, and trapezoidal waves with sufficient details and the related mathematical theories behind the subjects. ... the work is impressive in a mathematical sense. ... Square, triangular, and trapezoidal waveform analysis can be useful in many practical engineering and scientific environments, and this 160-page work is a good reference source for such a specific area."
