Noise eliminating system |
摘要 |
A noise eliminating system is disclosed for use in a radio receiver including a detector. The system comprises a differentiation circuit for differentiating the signal fed thereto from the detector, a clipper circuit for limiting the amplitude of the signal applied thereto from the differentiation circuit below a clipping level, a clipping level control circuit responsive to the strength of the electric field received in the receiver for varying the clipping level at a rate multiple of the electric field strength, means responsive to the electric field strength for selectively setting the rate at one of a plurality of values, and an integrating circuit for integrating signal fed thereto from the clipper circuit.
