Nyquist Sampling Theorem - Illinois Institute of Technology

Nyquist sampling rate is the rate which samples of the signal must be recorded in order to accurately reconstruct the sampled signal Must satisfy T0 2 fb or ?s =2?/ Ts >2 ?b Then xc(t) can be reconstructed perfectly from x[n]= x(n Ts) by using an ideal low-pass filter with cut-off frequency at fs/2 fs0 = 2 fb is called the Nyquist Sampling Rate Physical interpretation:

• When we sample at a rate which is greater than the Nyquist rate we say we are oversampling • If we are sampling a 100 Hz signal the Nyquist rate is 200 samples/second => x(t)=cos(2?(100)t+?/3) • If we sample at 2 5 times the Nyquist rate then f s = 500 samples/sec • This will yield a normalized frequency at 2?(100/500) = 0 4?

What is Nyquist sampling rate?

Nyquist sampling rate is the rate which samples of the signal must be recorded in order to accurately reconstruct the sampled signal A signal sampled every T0 seconds can be represented as: One way of understanding the importance of the Nyquist sampling rate is observing the fourier spectra of a sampled signal

What is the Nyquist criterion?

Simply stated, the Nyquist criterion requires that the sampling frequency be at least twice the highest frequency contained in the signal, or information about the signal will be lost. If the sampling frequency is less than twice the maximum analog signal frequency, a phenomenon known as aliasing will occur.

How to sample a bandpass signal at a rate less than bandwidth?

To examine the possibility of sampling a bandpass signal at a rate less than the total bandwidth, consider the system shown in figure (b). Assuming the w1 > w2 – w1, find the maximum value of T and the values of the constant A, wa and wb such that xr(t) = x(t). . . . 0 2?/T2?/T - w2 10U. Consider the system shown in figure (b).
