Sampling rate for a real signal, which is not band-limited?

WebIn real life continuous signals have frequencies that are beyond any sampling frequency possible, they might even contain infinte frequencies. One way round this is to pass the signal through a low pass filter that stops any frequencies above half the sampling frequency. This is still not perfect, but is a practical method.

"WebA low pass signal contains frequencies from 1 Hz to some higher value. Statement of the sampling theorem. 1)A band limited signal of finite energy , which has no frequency components higher than W hertz , is completely described by specifying the values of the signal at instants of time separated by $\frac{1}{2w}$ seconds and " - Signal sampling theorem

Signal sampling theorem

WebFeb 28, 2024 · Suppose we sample an 8 kHz sine wave at the commonly used rate of 48 kHz. The conditions of the sampling theorem are met since the sample rate is well above twice the maximum (and in this case only) frequency of the signal. Figure 1 shows one period of this sine wave with the sample points marked as red circles. WebMay 31, 2024 · Sampling theorem states that a band limited signal having no frequency components higher than fm hertz can be sampled if its sampling frequency is equal to or greater than Nyquist rate. Effect of Under sampling: ALIASING. It is the effect in which overlapping of a frequency components takes place at the frequency higher than Nyquist …

Websignal as shown, then after sampling the signal energy would appear to “fold back” at 1=2 the sampling rate. This can be used to demonstrate part of the Nyquist-Shannon sampling theorem: if the original signal were band limited to 1=2 the sampling rate then after aliasing there would be no overlapping energy, and thus no ambiguity caused by ...

WebJul 28, 2011 · By the bandpass sampling theorem, we do not need to use a sampler running at Fs>=2.02 MHz. Faster sampler implies more cost. By applying the bandpass sampling theorem, we can use a slower sampler and reduce the cost of the system. The bandwidth of the signal is 1.01MHz-0.99 MHz = 20 KHz. WebMar 15, 2024 · Sampling Question 12 Detailed Solution. Download Solution PDF. The maximum frequency of the band-limited signal. f m = 5 kHz. According to the Nyquist sampling theorem, the sampling frequency must be greater than the Nyquist frequency which is given as. f N = 2 f m = 2 × 5 = 10 kHz. So the sampling frequency f s ≥ f N.
