MATLAB lets you control a signal generator's modulation capabilities through Instrument Control Toolbox. You can also create a custom waveform in MATLAB, and then use the toolbox to upload the waveform to the signal generator.
在使用MATLAB生成混频信号时，首先需要明确信号的参数，如频率和周期数。设f1=80Hz和f2=100Hz作为两个不同频率的信号，周期数N=5。根据这些参数，可以计算出每个信号的持续时间t1和t2，分别为t1=5/80秒和t2=5/100秒。采样频率fs设置为2000Hz，确保采样符合奈奎斯特-香农采样定理。信号的时间数组t从0...
If your model uses a fixed-step solver, Simulink®uses the same step size for the entire simulation. In this case, the Signal Generator block output provides a uniformly sampled representation of the ideal waveform. If your model uses a variable-step solver, Simulink might use different step...
Define the Chirp Signal Generator Set the initial frequency of the chirp to be 0 Hz and the target frequency (frequency at the end of the sweep) to be 10 Hz. The frequency sweep is set to occur in the target time of 10 seconds. Given that the maximum instantaneous frequency of the si...

The output from this example shows that pink noise has approximately equal power in octave bands. Generate a single-channel signal of pink noise that is 44,100 samples in length. Set the random number generator to the default settings for reproducible results. Get pinkNoise = dsp.ColoredNoise...
According to the arbitrary waveform white light signal generator, a digital frequency synthesizer based on the DDS technology is adopted to be the signal generator, and the corresponding waveforms can be generated according to needs; besides, the arbitrary waveform white light signal generator has the...
Reset the random number generator for reproducible results. Generate a random signal where: The mean is constant in each of seven regions and changes abruptly from region to region. The variance is constant in each of five regions and changes abruptly from region to region. Get rng("default"...
Embed the pulse in white Gaussian noise such that the signal-to-noise ratio (SNR) is 53 dB. Reset the random number generator for reproducible results. Get rng default SNR = 53; y = randn(size(x))*std(x)/db2mag(SNR); s = x + y; Use the snr function to compute the SNR of ...
