摘要：
A method for limiting a signal in a radio transmitter comprises giving a signal a limiting threshold, taking at least two samples from the signal for obtaining sample values, adding one or more sample values between the obtained first and at least one subsequent sample values, searching for sample values exceeding the limiting threshold, and if at least one sample value exceeding the limiting threshold is found determining limiting coefficients for a predetermined number of sample values by means of the at least one sample value exceeding the limiting threshold, and limiting the signal by one or more determined coefficients.
