For the common-emitter amplifier shown below in the figure, let Vcc = 15V, R₁ = 27k2, R₂ = 15kQ2, RE = 2.4k2, and Rc = 3.9kQ2. The transistor has ß= 100. Calculate the dc bias current Ic, VCE and identify the operating mode for transistor. If the amplifier operates between a source for which Rsig = 2k2 and a load of 2k2, replace the transistor with its model, and find the values of Rin, Rout including R₁, and the overall voltage gain Vo/Vsig.
