The DCT, however, has better energy compaction than the DFT, with just a few of the transform coefficients representing the majority of the energy in the sequence.
This property of the DCT makes it useful in applications such as data communications and signal coding.
What is infinite Fourier sine transform?
The infinite Fourier sine troms form is denoted. by f(s) OR F (F()} and defined as. √(s) = √ # F(x)· sinsedx.

What is the Fourier transform of sine and cosine?
The Fourier Transform of the Sine and Cosine Functions
Equation [2] states that the fourier transform of the cosine function of frequency A is an impulse at f=A and f=-A.
That is, all the energy of a sinusoidal function of frequency A is entirely localized at the frequencies given by f=A.
What is finite Fourier cosine transform?
Similarly, the finite Fourier cosine transform of F (x),0 < x < l is defined. as. fc (p) = l. ∫
