  • Resampling and Comparison Setup—Contains the following options:Interpolation type—Contains the following options:Coerce—Sets each output sample value to equal the input sample value that is closest to it in time.Linear—(Default) Sets each output sample value to be a linear interpolation between the two input samples that are closest to it in time.Spline—Uses the spline interpolation algorithm to compute the resampled values.Filter based—Uses an interpolation method based on the convolution of the signal with a finite impulse response (FIR) filter.Operation—Specifies the arithmetic operation to perform. You can select from the following options:Add—(Default) Adds the input signals.Subtract—Subtracts the second input from the first.Multiply—Multiplies the first input by the second input.Divide—Divides the first input by the second input.FIR Filter Specifications—Contains the following options:Normalized bandwidth—[Interpolation type: Filter based] The normalized cut-off frequency of the FIR filter to use. The default is 0.4000.Alias rejection (dB)—[Interpolation type: Filter based] The minimum stopband attenuation of the FIR filter to use. The default is 80 dB.
