FOURIER TRANSFORM PAIRS
209CHAPTER11Fourier Transform PairsFor every time domain waveform there is a corresponding frequency domain waveform, and viceversa. For example, a rectangular pulse in the time domain coincides with a sinc function [i.e.,sin(x)/x] in the frequency domain. Duality provides that the rev[r]

A NEW BOHRNIKOL SKII INEQUALITY
The classical inequalities such as the inequalities of Bernstein, Bohr, Nikol’skii
and others play an important role in Analysis, the Approximation Theory and Applications
(see 8,14 16). Recall now the BohrFavard inequality: Let σ > 0,
1 ≤ p ≤ ∞, f ∈ C
m(R), supp ˆf ∩ (−σ, σ) = ∅, where ˆf is the F[r]
