Usually only a … WebFirst, you are taking fft of y4 which is sampled at 1000Hz. Check the following code to see how it can be dome properly Theme Copy f1=10; f2=30; f3=70; % twice the sampling rate Fs=2.05*70; % sampling frequency is a bit above 2 times to get all the peaks. Ts=1/Fs; Tn=0:Ts:1; fft_L=length (Tn);
WebThis frequency limit is known as the Nyquist frequency. When a digitized signal is analyzed, often by Fourier analysis, the power contained in the frequencies above the Nyquist frequency are added to lower frequency components. In fact, they are indistinguishable from those lower frequency components; hence the term 'aliasing.' WebIf we apply the Nyquist theorem to our 1 kHz cosine wave, 1 kHz x 2 = 2 kHz, we can see that 2 kHz is less than the 8 kHz sampling frequency that was used, therefore according to the Nyquist theorem, the 1 kHz signal is sufficiently represented.
Web29 aug. 2005 · A simple illustration of these processes can be seen in the case of the 800 Hz frequency aliasing to 200 Hz (see above). Suppose that the 800 Hz is an unwanted interfering signal caused by an unwanted mechanical vibration. To prevent its alias from causing significant data errors at 200 Hz, the 800 Hz frequency must be removed by a … Web20 aug. 2024 · clear; % a time vector with much much higher sampling frequency % to represent the original continuous time signal. time = [0 : 0.02 : 2]'; s3 = (-1) * sin …
