I am working on my final project for class and am STUCK! I am to design a 3 stage circuit with stage 1 and 2 using a 2N3904 transistor in a votlage divider config. and stage 3 using a darlington transistor in a voltage divider configuration leading to an 8 ohm speaker. I have stage 3 of the configuration done and I get the correct wattage out of the 8ohm speaker. But for the life of me I cant figure out how to determine the values for the resistors in stage 1 and 2 to give me the correct Vb in stage 3. Where do I start these calculations?
