Patent ID: 8892060

Claim:
A method for tuning a digital compensation filter within a transmitter, the method comprising: obtaining at least one resistance-capacitance (RC) detection result corresponding to a detected value representing a product of a resistance value and a capacitance value, wherein the digital compensation filter comprises an RC compensation module, and the RC compensation module comprises: a plurality of filtering units cascaded in series, wherein each filtering unit of the plurality of filtering units has a transfer function of H C,i (s)=(1+K RC *(s/w i )), wherein i represents an index associated to one of the filtering units, K RC represents the RC detection result, s=jw with j and w respectively representing an imaginary unit and an angular frequency, and w i represents a frequency parameter associated to one of the filtering units; and tuning the digital compensation filter by inputting the RC detection result into the RC compensation module.
