Instructions for Fourier Transform Simulator

• Step 1: Click on "Use Generated Signal" to generate the input signal.
• Step 2: Select the base signal from the dropdown menu, and enter the input signal frequency (in Hz), amplitude, and window duration (in seconds) in the parameters section.
• Step 3: Choose an operation (such as addition, multiplication, or convolution) from the "Operations" section.
• Step 4: Click the "Simulate" button to run the simulation.
• Step 5: Reset the simulator by clicking the "Reset Simulator" button.
• ⚠ Disclaimer: A Sinc window function is applied in this simulation. The sinc function acts as an ideal low-pass filter that perfectly isolates the frequency components of interest while smoothly removing others. Thus, after windowing with the Sinc function, the Fourier transform provides a frequency spectrum that still corresponds closely to the original signal. Window Duration (s) represents the time window over which the signal is considered (for example, a 0.2-second window), it would influence how the frequencies in the Fourier transform are spread out. A larger duration results in a more narrow frequency spread (better frequency resolution), while a smaller duration results in a more spread out frequency spectrum (lower frequency resolution).
