Digital Fourier Analysis: Fundamentals

Professor Kido is an internationally recognized expert in acoustics and engineering. Currently a professor at the Chiba Institute of Technology, Prof. Kido previously served as the Chairman of ONTEK R&D Co. Ltd., and earlier as the Director of the Research Center for Applied Information Sciences at Tohoku University. Prof. Kido was elected as a fellow of the Acoustical Society of America in 1978. He has published eight books in Japanese over a span of forty years.

• Preface.- Sine and Cosine Waves.- Fourier Series Expansion.- Numerical (sampled) Waveforms.- Discrete Fourier transform (DFT).- Fast Fourier transform (FFT).- DFT and spectrum.- Time window. Appendices.

"This first volume of a two-volume series explores, as the title implies, the fundamentals of digital Fourier analysis, including some advanced topics in the appendixes. ... Kido (Chiba Institute of Technology, Japan) does an excellent job of balancing a verbal explanation of the topics with mathematical formulas and equations. This combination makes the book very readable. ... Summing Up: Recommended. Upper-division undergraduates and graduate students." (S. L. Sullivan, Choice, Vol. 52 (10), June, 2015) "This short and to-the-point book comprises the following seven chapters, and is replete with marvelously clear and effective graphs and illustrations: 'Sine and Cosine Waves'; 'Fourier Series Expansion[s]'; 'Digitized Waveforms'; 'Discrete Fourier Transform (DFT)'; 'Fast Fourier Transform'; 'DFT and [Its] Spectrum'; and 'Time Window[s].' ... I recommend this excellent undergraduate textbook highly." (George Hacken, Computing Reviews, January, 2015)
