Capacitors in "Common Emitter Amplifier" Circuit ? Should i use Capacitors in "Common Emitter Amplifier" ( CEA ) Circuit ? As i saw many CEA circuits designed without any capacitors there ! And also hear that it's better to use two capacitors, one after the Voltage Source ( that feeds the Base ), And another Just before the another Voltage Source ( that feeds the Collector ). So, What do you think about that ? and why should is (use/don't use) them ?
