| Abstract: | There is a defect that the squelch sensitivity is not high in digital tuning receivers.The effects of loop filter in frequency synthesizer and the wiring of circuit board in practical de-sign on the receiver sensitivity are discussed. The problem is analyzed and the solution is proposed in the paper. |
