) for time domain IIR filtering approach, where P is the order of IIR filter. Under the same condition, compared with FIR filter, IIR filter always can fit frequency domain transfer function with fewer terms. The IIR filter proposed in this thesis only includes four items ( P 1 ), which is yet realized at the cost of bandwidth.
IIR Filter Design IIR filters are directly related to analog filters (continuous time) via a mapping of H(s) (CT) to H(z) (DT) that preserves many properties Analog filter design is sophisticated signal processing research since 1940s Design IIR filters via analog prototype need to learn some CT filter design
Impulses: FIR and IIR Delaying the input signal creates a Finite Impulse Response filter (FIR). Delaying the output signal creates an Infinite Impulse Response filter (IIR). IIR filter is essentially a feedback loop. 22 Impulses: FIR and IIR Filters work by using one or both of the following methods: D ela yc op fth i nus g ( bx m r
Comparison between IIR and FIR Filters Comparing the IIR and the FIR filters, neither has a definite advantage: IIR filters are implemented more efficiently than FIR filters in terms of number of operations and required storage Implementation of an IIR filter using the difference equation resulting from its transfer function is simple and
FIR IIR Filter Design software is intended to design IIR and FIR digital filters in a simple and fast way, in a user friendly environment. The filter type can be LP, HP, BP, and BS. . (see previous chapter) FIR IIR Filter Design counts filter graphs from the user defined filter coefficients. Some applications of this function: determining .
CHAPTER TWO BACKGROUND 2.1 IIR Digital Filters The analysis of roundoff noise for IIR filters proceeds in the same way as for FIR filters. The analysis for IIR filters is more complicated because roundoff noise computed internally must be propagated through a transfer function from the point of the quantization to the filter output.
IIR filters are digital filters with infinite impulse response. Unlike FIR filters, they have the feedback (a recursive part of a filter) and are known as recursive digital filters. Figure 2 Block diagrams of FIR and IIR filters For this reason IIR filters have much better frequency response than FIR filters of the same order. Unlike FIR .

GPS outages. To overcome these limitations, GPS can be integrated with a relatively environment-independent system, the inertial navigation system (INS). Currently, most integrated GPS/INS systems are based on differential GPS (DGPS) due to the high accuracy of differential mode (Petovello, 2003 and Nassar, 2003). More recently, GPS-
