Is the convolution integral is applicable only to LTI systems? I mean what is the condition that has to be imposed on the system so that to find the impulse response of it we can use convolution integral. To be more eloborate, should the system has to satisfy both the properties or any one is enough to find its impulse response using the convolution integral?

thnx
