Generating FSK Modulated Signals using MATLAB

Generating FSK Modulated Signals using MATLAB Experimental Requirements: (1) Randomly generate an array containing ten elements where each element is either 0 or 1, which will serve as the input data for the FSK signal. This can be implemented using MATLAB's randi() function: data = randi([0,1],1,10) to create a 1x10 binary array. (2) Perform FSK modulation on the binary data in the array, where 0 is modulated at 5000Hz and 1 is modulated at 8000Hz, with a symbol rate of 200 symbols/second. The implementation involves creating time vectors for each symbol duration (1/200 = 0.005 seconds) and generating sine waves at the corresponding frequencies using sin(2*pi*frequency*time) function. (3) Plot the generated FSK signal's time-domain waveform and frequency-domain representation. The frequency-domain analysis can be performed using MATLAB's fft() function followed by plotting the magnitude spectrum. To meet the experimental requirements, we first use MATLAB to randomly generate a ten-element array where each element is either 0 or 1. This array will serve as the input data for the FSK signal generation. We then perform FSK modulation on this binary data array. Specifically, we modulate 0s at 5000Hz and 1s at 8000Hz with a symbol rate of 200 symbols per second. The modulation process involves switching between two different carrier frequencies based on the binary input data, which is a fundamental characteristic of Frequency Shift Keying (FSK) modulation technique. Finally, we will plot the time-domain waveform and frequency-domain spectrum of the generated FSK signal to better understand and analyze the signal characteristics, including frequency components and time-domain behavior. The frequency-domain plot will clearly show the two distinct frequency components at 5000Hz and 8000Hz corresponding to the binary data elements.
