DSP System Design: Complexity Reduced IIR Filter by Artur Krukowski

By Artur Krukowski

DSP method Design provides the research of precise form of IIR polyphase filter out buildings mixed with frequency transformation concepts used for speedy, multi-rate filtering, and their program for customized fixed-point implementation. distinctive theoretical research of the polyphase IIR constitution has been awarded for 2 and 3 coefficients within the two-path association. This used to be then generalized for arbitrary filter out order and any variety of paths. using polyphase IIR constructions in decimation and interpolation is being offered and function assessed when it comes to the variety of calculations required for the given filter out specification and the simplicity of implementation. Specimen decimation clear out designs for use in Sigma-Delta lowpass and bandpass A/D converters are awarded which turn out to outperform different conventional methods.

DSP process Design can be of curiosity to graduate scholars, researchers, and pros circuit designers, who will require speedy and low-complexity electronic filters for either unmarried and multi-rate functions, in particular people with low-power specification.

Sample text

The SNR becomes [14]: The variation of the oversampled converter is the Sigma-Delta ADC. The name ADC is often used to describe the class of oversampled converters which employ single-bit quantizer with a noise shaping loop, coupled with a decimator as in Figure 1-30(c). Such an ADC is known as Pulse Density Modulation (PDM) ADC as at every time the relative density of single bit tracks the input amplitude. In ADCs the amplitude resolution, sacrificed by the crude quantization, is trade with the temporal resolution.

For this case we start from: After cross-multiplication and algebraic manipulation of the polynomial coefficients we obtain another set of linear equations for calculating the gain factor preceding each first-order allpass section and the numerator coefficients of the remaining part of the original transfer function. Assuming boundary conditions and these linear equations with vector of unknowns, X, can be expressed as: There is an easy way of converting the IIR structure of Figure l-27(a) directly into an allpass form of Figure 1-27(b) that is fast and does not suffer from the loss of precision.

As shown in Figure 1-25 the main difference between the oversampled PCM ADC and the PDM ADC is the insertion of the loop filter H(z) and a one-bit quantizer with a negative feedback loop to shape the large quantization noise. 1. Polyphase IIR Filters The low-resolution quantization is first provided by a modulator operating at the high rate, Then the decimator decreases the sample rate but increases the resolution in amplitude. The aim of the modulator is to produce a binary bit signal, which average tracks the analog input signal.
