AMPLIFIER WITH NOISE REDUCTION
First Claim
1. A system comprising:
- (a) a switch including;
(i) a first state for allowing passage of a signal therethrough; and
(ii) a second state for preventing passage of the signal therethrough; and
(b) a detection circuit in communication with the switch, the detection circuit configured to;
(i) detect whether the signal includes an amplitude of at east a predetermined level;
(ii) operate the switch to the first state if the amplitude of the signal is at least the predetermined level; and
(iii) operate the switch to the second state if the amplitude of the signal is less than the predetermined level, wherein operation of the switch to the second state is delayed by a predetermined period of time.

Abstract
The present invention helps eliminate ingress noise addition (i.e., the “noise funneling effect” for an HFC coaxial plant). A system according to various aspects of the present invention comprises a switch that includes: (i) a first state for allowing passage of a signal therethrough; and (ii) a second state for preventing passage of the signal therethrough. The system further includes a detection circuit in communication with the switch. The detection circuit is configured to: (i) detect whether the signal includes an amplitude of at least a predetermined level; (ii) operate the switch to the first state if the amplitude of the signal is at least the predetermined level; and (iii) operate the switch to the second state if the amplitude of the signal is less than the predetermined level, wherein operation of the switch to the second state is delayed by a predetermined period of time.
