SINC(X)

• is any real number.

Description

• This function shows the value of the cardinal sin function.
• In , is any real number.
• The full name of the function is sine cardinal,but it is commonly referred to by its abbreviation, Sinc.
• The unnormalized SINC function is defined by :

• The normalized SINC function is defined by $\displaystyle SINC(X)= \frac{SIN(\pi)x}{\pix}$ .
• The value at x = 0 is defined to be the limiting value Sinc(0) = 1.
• The only difference between the two definitions is in the scaling of the independent variable (the x-axis) by a factor of π.
