A common emitter amplifier is set up using an ideal BJT. If r = 1.2kN, the biasing resistors are 20 kn and 100 kN, with 3 = 300, & the coupling capacitors are 0.1 µF each, then with R. = 2.2kN, the breakaway frequencies at the lower range of the frequency response would be 1.4 kHz 813 Hz 653 Hz 1.9 kHz 1.6 kHz 723 Hz 1.3 kHz
