The discrete Fourier transform is an invertible, linear transformation with denoting the set of complex numbers. Its inverse is known as Inverse Discrete Fourier Transform (IDFT). In other words, for any , an N-dimensional complex vector has a DFT and an IDFT which are in turn -dimensional complex vectors. The inverse transform is given by: A square wave is a non-sinusoidal periodic waveform in which the amplitude alternates at a steady frequency between fixed minimum and maximum values, with the same duration at minimum and maximum. In an ideal square wave, the transitions between minimum and maximum are instantaneous. The square wave is a special case of a pulse wave which allows arbitrary durat… WebASK AN EXPERT.
