Fixed point iir
Web7.4.9. IIR: Full-rate Fixed-point. This design example implements a full-rate fixed-point IIR filter. This design demonstrates a single-channel second-order Infinite Impulse Response (IIR) filter running at the clock rate. Usually with such designs, closing the feedback loop is difficult at high clock rates. WebIn a floating-point implementation, construction of sections is not relevant. In a fixed-point implementation, assigning filter zeros and poles to sections may decide whether range overflow occurs or not. Building an optimal cascade structure for a fixed-point IIR implementation is a complex task.
