Abstract :
A transfer function of an odd order maximally flat FIR (finite impulse response) lowpass filter is proposed. The frequency response of the filters described by this transfer function are different from those of the even order maximally flat filters. The general form of the transfer function describing the even and odd order maximally flat FIR lowpass filters is also proposed. This general form is available for designing the optimal maximally flat filter which meets the given specification with consideration of even and odd order. Consequently, the optimal transfer function to meet a given specification has been obtained
