    • Electronusa Mechanical System [Research Center for Electronic and Mechanical]1 | P a g eThe Impedance Matching in The Audio Signal ProcessingUmar Sidik.BEng.MSc*Director of EngineeringElectronusa Mechanical System (CTRONICS)*umar.sidik@engineer.com1. IntroductionCommonly, impedance is obstruction to transfer energy in the electronic circuit. Therefore, theimpedance matching is required to achieve the maximum power transfer. Furthermore, theimpedance matching equalizes the source impedance and load impedance. In other hand, theemitter-follower (common-collector) provides the impedance matching delivered from the base(input) to the emitter (output). The emitter-follower has high input resistance and low outputresistance. In the emitter-follower, the input resistance depends on the load resistance, while theoutput resistance depends on the source resistance. In addition, this study implements the radialelectrolytic capacitor 1000ߤ‫ܨ‬ 100ܸ⁄ .2. Analytical WorkIn this study, ܴଵ and ܴଶ form the Thevenin voltage, while ‫ܥ‬ଵ and ‫ܥ‬ଶ deliver ac signal as ‫ݒ‬௜௡ and‫ݒ‬௢௨௧(figure 1).(a) (b)Figure 1. (a).
