Abstract
Systems and methods are provided for generating a phase compensated numerically controlled signal using a fixed-point algorithm. In one example, a method includes receiving, at a downhole device, parameters including an input frequency and a compensation value. The method further includes converting, based on the parameters, the input frequency to a delta phase value. The method also includes calculating, with the downhole device, an accumulation error for a digital signal. In response to determining that the accumulation error is greater than or equal to the compensation value, the method removes the accumulation error from the digital signal to generate an output signal.
