## What is the Fourier transform of a sine wave?

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.

**Why is the Fourier transform of Dirac delta 1?**

The physical intuition is that the “delta function” is “infinitely concentrated” in the time domain, so its Fourier transform should be “completely spread out” in the frequency domain. Show activity on this post. for all f∈S. Hence, ˜δ=1.

**Are sinc functions integrable?**

Although sinc(י) is bounded, it is not absolutely integrable.

### What are Fourier sine and cosine transform pairs?

In mathematics, the Fourier sine and cosine transforms are forms of the Fourier transform that do not use complex numbers or require negative frequency. They are the forms originally used by Joseph Fourier and are still preferred in some applications, such as signal processing or statistics.

### Is Dirac delta function a function?

The Dirac delta is not a function in the traditional sense as no function defined on the real numbers has these properties. The Dirac delta function can be rigorously defined either as a distribution or as a measure.

**What is Fourier series and Fourier transform?**

The Fourier series is used to represent a periodic function by a discrete sum of complex exponentials, while the Fourier transform is then used to represent a general, nonperiodic function by a continuous superposition or integral of complex exponentials.
