Claim 6:
7. The method for amplitude estimation according to claim 1, wherein the step of determining, based on a preset intermediate variable parameter, the current angle upper limit value, and the current angle lower limit value, a next angle amplification factor and a next flag parameter that are corresponding to a next iteration step, when the target difference is greater than a preset precision threshold comprises:
when the target difference is greater than the precision threshold, obtaining a variable parameter in the current iteration step, reducing the variable parameter in the current iteration step by a preset value, and determining the reduced variable parameter as an intermediate variable parameter corresponding to the next iteration step;
determining a next angle maximum value based on the current angle upper limit value and the intermediate variable parameter;
determining a next angle minimum value based on the current angle lower limit value and the intermediate variable parameter; and
determining, based on the next angle maximum value and the next angle minimum value, the next angle amplification factor and the next flag parameter that are corresponding to the next iteration step.
