| Summary |
"There are many communication and electronic circuits, such as filters, phase-shifting networks, matching networks, voltage amplifiers with and without feedback, whose proper usage with associated equipment depends upon the knowledge of the variation with frequency of the voltage ratio and phase angle between the output and input sinusoidal voltages or currents...It is the purpose of this thesis to design and build an electronic instrument that will measure the voltage gain and phase angle between two sinusoidal voltages or current of communication circuits, in such a manner as to aid the student in visualizing how these quantities vary with frequency, and to increase the accuracy of the phase angle measurements. This instrument, the gain-phase meter, will be designed to give a phase angle accuracy of ±1.0 degree or better, and gain accuracy of ±5% or better, for input voltages from .5 to 62.5 volts over a frequency range for 40 to 10,000 cycles per second. Though several high accuracy electronic phase meters have been constructed, the author of this thesis feels that none are of the type that fulfill the above objectives"--Introduction, leaves 1-2. |
