Abstract:
A three phase power supply for use in powering a three phase gyro comprising:clock signal generating means for generating a system clock signal;counter means for receiving said system clock signal, said counter means, responsive to said system clock signal, generating a plurality of addresses and a digital-to-analog conversion clock signal;memory means for receiving said plurality of addresses, said memory means, responsive to said plurality of addresses, generating a plurality of binary data bytes representative of a three phase sine wave signal having first, second and third phases and a predetermined frequency;digital-to-analog converter means for receiving said digital-to-analog conversion clock signal and said plurality of binary data bytes, said digital-to-analog converter means, responsive to said digital-to-analog conversion clock signal, converting said plurality of binary data bytes to said three phase sine wave signal; andamplifying means for amplifying said three phase sine wave signal, said amplifying means including filtering means for attenuating selected undesirable frequencies within said three phase sine wave signal to eliminate distortion effects from said three phase sine wave signal.
