摘要
The invention relates to a method and a circuit for digitally correcting the frequency of a signal, especially for use in a transmitter/receiver circuit. The frequency of a complex digital signal is corrected by rotating the signal 'pointer' (i0, q0) about a predetermined angle in the complex I/Q plane according to a correction frequency, by means of the CORDIC algorithm. The CORDIC algorithm has microrotation blocks (11-13) and a character table (14) and a register (31) according to its N-stages.
