fsk的matlab实现代码，很详细的．

详 情 说 明

Here is a more detailed description of the implementation of fsk using MATLAB:

Frequency-shift keying (FSK) is a modulation technique that uses frequency modulation to encode digital information. In this particular implementation, we have used MATLAB to create the FSK code. The code is detailed and well-organized, making it easy to understand and modify.

To begin, we defined the frequency deviation as the difference between the carrier frequency and the two possible frequency states. We then created two waveforms, one for each frequency state, and modulated them with the binary input data to produce a composite FSK signal. This signal was then plotted using the MATLAB plot function.

Next, we added noise to the signal to simulate real-world conditions. We also included a demodulation function to convert the FSK signal back into binary data. This was done by using a bandpass filter to extract the two frequency components from the FSK signal, and then comparing their amplitudes to determine the binary data.

Overall, this MATLAB implementation of FSK is detailed, easy to understand, and highly functional. It can be modified to suit a variety of different applications and use cases.
