Abstract
The interpolated FIR (IFIR) technique has been shown to be very useful in designing narrow band lowpass filters. The IFIR filters enjoys significant saving in the number of multipliers and can be implemented efficiently. In the case when an desired filter (non-IFIR) is given as in some applications, e.g., matched filters, we propose the use of IFIR filters to approximate the desired filter. An iterative approach to the design of IFIR approximation filters in the least square sense is presented
