Short notes
Permutability of cosine and sine Fourier transforms
A. V. Pavlov MIREA — Russian Technological University, Moscow
Abstract:
It is proved that the cosine and sine Fourier transforms are permutable with the opposite sign on the positive real axis. This property implies that the cosine and sine Fourier transforms coincide in absolute value on the semiaxis for a wide class of functions.
Key words:
Fourier transform, permutability cosine and sine Fourier transforms, coincidence of cosine and sine Fourier transforms.
