Examples of Fourier Transform with Diagram
Let’s consider the following example circuit:
Here the input to the circuit is a square wave, and the output is an filtered square wave. Where the Fourier transform of the input square wave is a series of impulses at the harmonic frequencies. The Fourier transform of the output square wave is a series of attenuated impulses at the harmonic frequencies.
Here are the following diagram which shows the Fourier transforms of the input and output signals:
Fourier Transform in Circuit Analysis
In this article, we will study about the Fourier transform analysis or Fourier Transform in Circuit Analysis. The Fourier transform is basically a mathematical operation that decomposes a signal into its constituent frequency components. In simple words, it converts a signal from the time domain to the frequency domain. The time domain will represent the signal as a function of time, while the frequency domain represents the signal as a function of frequency.
