Spectral Estimation Techniques: Correlogram, Blackman–Tukey, Windowed Periodogram, Bartlett, and Welch Methods

  • Input Parameters:
    • Input Signal(s): Enter the signal frequency (Hz), sampling frequency (Hz), and the signal length. For rectangular or triangular pulse signals, also specify the pulse width in seconds.
    • Window Type: Select a window type (e.g., Rectangular, Hann, Hamming) from the dropdown menu, and provide the window size.
    • SNR (in dB): Enter the desired Signal-to-Noise Ratio (SNR) in decibels (dB).

  • Steps:

  • 1. Generate Input Signal(s): Click the “Generate Input Signal” button to create the input signal. Choose a base signal (e.g., sine or cosine), and provide the frequency (Hz), sampling frequency (Hz), signal length, window type, and window size.
  • 2. Display the PSD Plot: Click the “Simulate” button to view the power spectral density (PSD) plot of the noisy input signal.
