摘要
A reconfigurable infinite impulse response low-pass filter is described in which the frequency response can be changed by changing a single parameter while the filter gain of the filter remains constant, preferably, unity. The parameter value is used to calculate the coefficients for the infinite impulse response filter. By choosing the parameter values carefully, the infinite impulse response filter can be implemented using shift registers rather than multipliers to reduce the hardware complexity of the infinite impulse response filter.
