What is the Nyquist rate of rectangular pulse?

(a) The Nyquist rate is 2 × 4.5 × 106 9 MHz.

What is Nyquist criteria condition for sampling?

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.

What is the Nyquist rule for sampling rate?

The rule which states that a digital sampling system must have a sample rate at least twice as high as that of the highest audio frequency being sampled, in order to avoid aliasing and thus reproduce the wanted audio perfectly.

What is the problem with sampling at Nyquist rate?

The difficulty with the Nyquist-Shannon sampling theorem is that it is based on the notion that the signal to be sampled must be perfectly band limited. This property of the theorem is unfortunate because no real world signal is truly and perfectly band limited.
