I have a doubt in Convolution

if I have two functions w and s1,
w is my sine signal, and s1 is my gaussian. Both have maximum value of 1, if i do convolution of both of them

conv(w,s1)

Is it possible to get a maximum value more than 1

Thanks

Yes, since convolution involves summation as well as multiplication.
