Common Waveform Analysis, which will be of interest to both electrical engineers and mathematicians, applies the classic Fourier analysis to common waveforms. The following questions are answered: • Can a signal be considered a superposition of common waveforms with different frequencies? • How can a signal be decomposed into a series of common waveforms? • How can a signal best be approximated using finite common waveforms? • How can a combination of common waveforms that equals a given signal at N uniform points be found? • Can common waveforms be used in techniques that have traditionally been based on sine-cosine functions? Common Waveform Analysis represents the most advanced research available to research scientists and scholars working in fields related to the area.
