In order to perform a FFT on a signal it is required to pad the signal so that the number of elements in it is of power of 2.

Is the following property true (X - Fourier transform)?

It is not possible to construct an ideal filter.

Parseval's identity is analogous to Pythagorean theorem.

What is the inverse Fourier transform of:

Run-length coding is an efficient method to compress black and white images.

Signals are often transformed to frequency domain to perform speed up filtering (using Convolution theorem).

In order to enhance the detail in your image you should use a high pass filter.

Using entropic coding it is possible to represent a symbol with less number of bits than the entropy (on average).

Not all active SAR systems are side-looking.
