The Conv Dialog box

Signal	Specifies the signal, which will be convoluted with the response.
Response	Specifies the response, which will be convoluted with the signal.
Sampling Interval	Specifies the sampling interval. The default is <auto>, which corresponds to an automatically-computed interval.
Options	Specifies the computation options Normalize Response Specifies whether the response should be normalized to [0, 1], before it is used to calculate the convolution. The response is normalized by $\frac{x_i}{sqrt(\sum _ix_i^2 \,\!)}, i = 1, 2, 3, ...$ where $x i$ is the ith value in the response. Wrap Response Specifies whether the response should be wrapped], before it is used to calculate the convolution. If this is selected, the maximum data point in the original response will become the first data point in the wrapped response. Convolution Type Specifies whether the convolution is linear or circular. Linear Linear convolution will be computed. Data points outside the input range will be viewed as zeros. Circular Circular convolution will be computed. Data points outside the input range will be viewed as repetition of the data points within the range.
Output	Specifies the output range.
