Fourier Series, Distortion and Fourier Spectrum using TINA

Fourier Analysis

In addition to the calculation and display of the time response, TINA calculates the coefficients of the Fourier series and the harmonic distortion of periodic signals using the Fast-Fourier Transform. The Fourier series is presented both in exponential and trigonometric form. You can set the sampling start time, the number of samples, and the number of harmonics. Using TINA's supplementary hardware, you can actually measure the harmonic distortion and the amplitudes of Fourier coefficients. in a real circuit.

Fourier Spectrum

Once the time response of a circuit is obtained, the continuous spectrum of non-periodic signals can also be calculated using Fourier analysis. The spectrum is displayed in a dual panel diagram either as amplitude and phase or as the amplitude of cosinusoidal and sinusoidal components. You can define the number of FFT sampling points, the start and end times of the sampling, and the maximum and minimum frequencies to be displayed.
