METHOD FOR DIVIDING A NUMBER BY A FRACTION HAVING A NUMBER IN THE FORM OF A POWER OF 2 AT THE NUMERATOR

摘要

A method divides a number N1 by a number which can be written in the form 2ⁿ/k, n and k being whole numbers, and obtains a result N2. The result N2 is calculated by adding terms N1*Ki/2^n-i for i ranging from 0 to N, the terms Ki being the constituent bits K0, K1, K2, . . . K_N-1 of the number k expressed in binary. The method can be applied particularly to the production of a calibration circuit for calibrating a clock signal in a UHF transponder.
