Weblower series inductance at high frequency than a single bigger capacitor. The most common values bypass capacitors are: 47 µF, 22 µF, 4.7 µF, 0.1 µF, and 0.001 µF. The higher value capacitors (47 µF and 4.7 µF) work well at relatively low frequency (low-frequency bypass). The 0.1 µF targets the middle frequency range, while the 0.001 µFor http://www.nerdkits.com/forum/thread/1598/
WebJul 16, 2024 · The bypass capacitor is an attempt to make voltage gain for AC signals larger than the DC gain set by Rc and Re. It adds problems and it solves some problems and is very much a mixed blessing. Input impedance for AC signals pretty much falls to the value when not using an emitter resistor.
