The invention relates to a circuit for producing output signals which indicate a fraction of a series of input signals, comprising means for providing a first value equivalent to the value of a numerator of the fraction, means for providing a second value equivalent to the value of the difference between a numerator of the fraction and a denominator of the fraction, means for subtracting in sequence the second value from the first value for each input signal of the series until a result of zero or less is produced, means (17) for adding in sequence the first value to the result corresponding to each input signal of the series until a result greater than zero is produced, and means for using the value of the result to indicate whether each signal of the series of input signals is to be used. <IMAGE>
