METHOD FOR ADJUSTING DEMODULATION WAVEFORM

摘要

PURPOSE: A demodulation waveform adjusting method is provided to reduce both a trouble and a time of adjusting a receiver data waveform. CONSTITUTION: In a demodulation waveform adjusting method comprises adjusting a receiver data waveform automatically according to a vector diode without adjusting a quadrature coil and a trimmer capacitor by use of a DECT RX IC(Siemens 5th chip set:PMB 5420). At a slot before a receiver data reception, a DC potential is generated at a terminal(TAC)(precharge mode), and a potential is charged at the sample hold capacitor(SHC) port capacitor. A potential is applied to the vector diode so as to be varied a capacitance in the diode.
