Objectives of this experiment:
1. To Construct and properly adjust a balanced modulator, and study its operation.
2. To observe that the output is a double side band, with a suppressed-carrier signal.
3. To adjust it for optimum carrier suppression.
4. To verify that the input audio-level directly affects the double side-band output amplitude.
5. To observe that the output is minimum with zero audio input. 6. To measure carrier only output and the peak side-band output, and to calculate the carrier suppression.

Built in regulated power supply: + 12V/300mA.
