1.	The frequency f1 and f2 from the below picture are respectively called ___________(a) lower cut-off frequency and upper cut-off frequency(b) upper cut-off frequency and lower cut-off frequency(c) left frequency, right frequency(d) there is no specific nameI had been asked this question by my school teacher while I was bunking the class.I'm obligated to ask this question of General Frequency Consideration topic in chapter Transistor Biasing and Low Frequencies of Analog Circuits
Answer» Right answer is (a) lower cut-off FREQUENCY and upper cut-off frequency To elaborate: The frequencies are CALLED lower cut-off frequency and upper cut-off frequency. At these frequencies power of the SIGNAL becomes half of its original value, 3dB LESS than the MAXIMUM and they are also called 3dB cut-off frequencies.
