According to the output of the signal source set the center frequency of the FFT plot to 1 MHz and set the horizontal scale to 5 kHz to provide a clear view of the output. I t vsin 2f i t The carrier signal is represented as. Begin increasing the amplitude of the oscillator output starting from near zero while watching the carrier component of the analyzer display.
According to the output of the signal source set the center frequency of the FFT plot to 1 MHz and set the horizontal scale to 5 kHz to provide a clear view of the output.
Assigning base frequencies in increments of 02 MHz gives each station 100 kHz of room on either side of the center frequency for its frequency modulation. Therefore deviation 5 350. Total AM signal power in Watts 48. Fm Modulation Index 25 Formula or equations used for Modulation Index Calculator.
