Abstract:
1. A method of processing an input signal comprising: filtering first frequency components from the input signal using a filter in a first signal processing branch that receives and filters the input signal leaving a first remaining portion of the input signal, the first signal processing branch having an amplifier that amplifies the input signal in the first signal processing branch with a frequency response that passes signals in a frequency range of the first remaining portion; filtering second frequency components from the input signal using a filter in a second signal processing branch that receives and filters the input signal leaving a second remaining portion of the input signal, the second signal processing branch having an amplifier that amplifies the input signal in the second signal processing branch with a frequency response that passes signals in a frequency range of the second remaining portion; processing the first remaining portion in the first signal processing branch while processing the second remaining portion in the second signal processing branch to obtain first and second processed signal portions; and combining the first and second processed signal portions to obtain an output signal indicative of the input signal.
