Design a one stage amplifier AM (Amplitude Modulation) receiver with centre frequency fc at 460 kHz and Q = 100. Use transistor schematic diagram similar to Figure 1 and L = 1.2mH. The small signal parameters are rπ = 2kΩ, β = 50 and r0 =10 kΩ. Then, determine the upper cutoff frequency fH, lower cutoff frequency fL and bandwidth.

I don't even know how to start designing, mind shed some light?

Hi I have successfully find the upper cutoff frequency fH, lower cutoff frequency fL and bandwidth. So, what the next step,how the basic circuit looks like? i mean, what value of resistor/arrangement of it?

after calculation,my C=100pF, BW=4600Hz, fL=457.7kHz, fU=462.3kHz
