1. An apparatus comprising:
- a variable bandwidth filter having;
a data input for receiving an input signal;
a data output for generating an output signal; and
a control input for receiving a bandwidth control signal;
wherein;
a bandwidth of the variable bandwidth filter is in conformity with the bandwidth control signal;
the output signal is generated by filtering the input signal in conformity with the bandwidth of the variable bandwidth filter; and
the the bandwidth control signal is generated based on an integrated error between the input signal and the output signal.
