In this project work, you will design an AM radio receiver. You are free to choose any design you want with the following constraints:

1. Your input signal has a magnitude of 5-10 uV.
2. You are only allowed to use 110VAC source (that is you should obtain the bias DC voltages by designing appropriate power supplies).
3. Your output signal power should be 0.25W into the 8W speaker.

The deadline for project report and demonstration is the last laboratory session. You are also expected to give a brief 5 minute presentation about your work with transparencies at the same time.

GRADING POLICY:

1. If you can only make your demonstration with an input signal generated from WAVETEK (a single tone input), you can get at most 15 points.
2. If you can achieve to receive a single AM radio station, you will get at most the full credit point which is 20 points.
3. If you can achieve to receive 5 preset stations (you will determine the frequencies), you will get 5 bonus points. In this case you can get 25 points if your report and demonstration is sufficient enough.
4. If you can make a continuously tunable radio receiver, you will get 10 bonus points. In this case you can get 30 points if your report and demonstration is sufficient enough.
5. If you can not demonstrate your circuitry on PCB, but you make your demonstration on breadboard, then you will lose 5 points (i.e. if you show the 3^rd option with 5 preset stations on breadboard, you can get full credit which is 20).

6. All students enrolled in both EE 121 and EE 169 may elect to transfer any amount of extra points (above 20) to the EE 121 class.
7. All students who are enrolled in EE 121 but not in EE 169 may participate in the project. The extra credit will be the above grading system minus 5 points.
