2? . Hence the Fourier transform of the delta function is a constant function. From here we can immediately obtain invoking the duality principle
Step functions and constant signals by allowing impulses in F(f) we can define the Fourier transform of a step function or a constant signal unit step.
concentrated at x = 0 whereas its Fourier transform is a constant function for all x ? R
Fourier transforms and spatial frequencies in 2D function is a sinusoid with this frequency along the direction and constant perpendicular to.
The function and the modulus squared ?. ?f˜(?). ?. ?2 of its Fourier transform are then: Figure 2. An underdamped oscillator and its power spectrum (modulus

2. Suppose that f is absolutely integrable show that ˆf is a bounded
is an odd function of f and hence the value of the integral is zero. Low-pass High-pass Products: Let g(t) be signal whose Fourier transform satisfies.
