INTEGRAL EQUATIONS OF CONVOLUTION TYPE


Solving of Integral equations of convolution type

 

Definition: An integral equation of the form

 y(t) = f(t) + 0ʃt F(t − u) G(u) du

 is called an integral equation of convolution type.

This equation can also be expressed as

 y(t) = f(t) + F(t) * G (t).

 

PROBLEMS BASED ON INTEGRAL EQUATIONS OF CONVOLUTION TYPE

 

Example 16: Solve the integral equation

 y (t) = 1 + 0ʃt y(u) sin (t − u) du

Solution: The given equation can be written as

y (t) = 1+ y(t) * sin t

 L[y (t)] = L[1] + L[y (t)* sint]

= 1/S + L[y (t)] L [sin t]
