Filtering
•
Filters limit Bandwidth to reject unwanted signals, preventing them from
adversely effecting performance
•
The Automatic Gain Control (AGC) System attempts to maximize Dynamic
Range within Weak Signal Receiver Stages
•
Critical to maintain linearity to prevent distortion products
•
DSP Adaptive Filters are use to reduce noise which improves S/N Ratio
