Abstract

This paper proposes the development of a microcontroller-based scheme that can be used both as a frequency synthesizer and a vector voltmeter. The scheme employs direct digital synthesis for development of the frequency synthesizer and the synchronous detection technique for developing the vector voltmeter. The system also employs correction polynomials to compensate for errors in practical voltage readings. The final corrected readings of the system have been found to closely match with the true readings.
