Write A Function To Calculate The Normalized Sinc

Normalized sinc function, also known as raised cosine function, is widely used in signal processing and data analysis. It’s crucial for understanding and manipulating signals in various fields, including telecommunications and image processing.

How to Use This Calculator

1. Enter the value of X.
2. Enter the value of N.
3. Click ‘Calculate’.

Formula & Methodology

The normalized sinc function is defined as:

sinc(x) = sin(πx) / (πx)

In this calculator, we use the raised cosine function, which is a normalized version of the sinc function:

sinc(x, N) = sin(πx / N) / (πx / N)
