Explanation & Usage:
This simulator may be used to generate and manipulate: Sine Wave (+Sine Wave), Square Wave, Psuedo-Random (+Sine Wave), and Amplitude Modulated Signals (of both Carrier and Modulator as sine waves, as well as, Pseudo-Random Modulator + Sine Wave Carrier).
Signal Parameters such as amplitude and frequency, can be manipulated via the sliders to obtain the desired values.
Data Acquisition Parameters such as Number of Lines and Fmax may also be changed. # Line options have been fixed in the drop-down menu to represent the Radix-2 FFT algorithm requirements, which is in use in most Vibration Analysis Portable Condition Monitoring Data Collectors. Furthermore, to simulate real-life situations, a computed spectrum of 1.28 times the displayed spectrum, is utilized. This means that, aliasing will not occur just beyond the (displayed) Fmax, but rather the folding back of the signal (aliasing) will not occur until the signals' frequency is higher than the computed spectrum's frequency range. Finally, negative aliasing may also be achieved, just below the 0 Hz marker.
In the FFT Spectrum plot, the user can change the Y-Scale maximum value, as well as Toggle to view in Log Scale (with Y-Scale fixed to 100).
The Root-Mean-Square (RMS) value of the displayed data is calculated for both the Time Waveform, as well as, the FFT Spectrum.
