Using entropic coding it is possible to represent a symbol with less number of bits than the entropy (on average).
Is the following property true (X - Fourier transform)?
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.
Signals are often transformed to frequency domain to perform speed up filtering (using Convolution theorem).
It is not possible to construct an ideal filter.
Not all active SAR systems are side-looking.
Parseval's identity is analogous to Pythagorean theorem.
Run-length coding is an efficient method to compress black and white images.
In order to enhance the detail in your image you should use a high pass filter.
