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开始，
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.
The Signal Generator block can produce one of four different waveforms: sine square sawtooth randomYou can express signal parameters in hertz or radians per second.

MATLAB Online에서 열기 We have to generate 128 samples of sinusoid with frequency of 3000 Hz, amplitude of 0.8 and sampling rate is 8000 Hz.The correct codes were: >> Fs = 8000; >> t = [0:127]/Fs; >> y = 0.8*sin(2*pi*3000*t); ...
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...
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"...
Provide randobject in a known state as an input to awgn except when the input is a dlarray object. For more information, see RandStream. To reproduce CPU random number streams on a GPU, the random number generator used on both must align. For more information, see Random Number Streams on...
The pink noise has roughly equal power in octave bands. Rerun the preceding code with'InverseFrequencyPower'equal to 0, which generates a white noise signal. A white noise signal has a flat power spectral density, or equal power per unit frequency. Set the random number generator to the defa...
