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
