FIR Filter Type: Gaussian
BT Values: 0.1 to 0.9
This low pass filter is commonly used in communications applications. The Gaussian filter follows the following formula:
where
f = Frequency (fraction of the IQ Rate)
Use the Gaussian Filter BT property or the NIFGEN_ATTR_OSP_FIR_FILTER_GAUSSIAN_BT attribute to set the BT value.
The following diagram shows an ideal Gaussian filter response with a BT of 0.3. The frequency axis is scaled as a fraction of the IQ Rate.
