    hi, i need to design a common emitter amplifier with:
    d.c supply 15V
    gain 200
    low frequency cut-off 50Hz
    signal source impedance 600 ohms
    transistor to be used 2N2222

    i have done the gain part but am lost in the rest of the workings:confused:
    any help would be appreciated:)

    Below is my circuit diagram

    I have set RC to be a 2K and Re to be 10ohm to give me a gain of 200.

    Hi,

    We need to see your circuit and results before we can give help.

    You may find the suggestions contained in the How to post guide that will give you some ideas on the type of information that would be beneficial to provide as part of your post.

    You need to follow the advice of both beenthere and hgmjr. Without the circuit daigram and the workings you have done so far there is little anyone can help you with.

    Smokey ...

    You might want to tell us the values you selected for each component on the diagram.
