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 .
  • 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.

Examples

  1. SINC(9) = 0.04579094280463962
  2. SINC(-34) = 0.015561255474118348
  3. SINC(-51.7) = 0.019163025320677915
