A signal represented by the following function is the input to a filter: 10∗sin(t) The output of the filter can be represented by the following function: 10∗sin(t) Another signal represented by the following function is the input to the same filter: 10∗sin(30∗t) The output of the filter can be represented by the following function: 0.1∗sin(30∗t+3) The filter could be:
A. Low pass
B. High pass
C. Band pass
D. Band stop
