40th Annual Frequency Control Symposium - 1986 Performance Analysis of the PJumericaIIy Controlled Oscillator
Elizabeth C. Kisenwether, William C. Troxell · 1986
Summary With the advances in high-speed VLSl and VHSIC: logic, use of digital logic in high speed oscillator design is now possible. One design approach is the numerically controlled oscillator (NCO), where continuous summations of step size K are made to the previous accumulator value. Overflow of the accumulator results in an output at the desired periodic rate. This paper addresses operation of the direct synthesis NCO including frequency determination and control, phase
