1. 1. FPGA Implementation of Flexible Interpolators and Decimators

   University essay from Elektroniksystem; Tekniska högskolan

   Author : Dabbugottu VenkataVikram; [2013]
   Keywords : Interpolation; Decimation; Linear-phase FIR interpolation; VHDL implementation of interpolators and decimators;

   Abstract : The aim of this thesis is to implement flexible interpolators and decimators onField Programmable Gate Array (FPGA). Interpolators and decimators of differentwordlengths (WL) are implemented in VHDL. The Farrow structure is usedfor the realization of the polyphase components of the interpolation/decimationfilters.

3. 2. Tree-Structured Linear-Phase Nyquist FIR Filter Interpolators and Decimators

   University essay from Elektroniksystem; Tekniska högskolan

   Author : Jimmie Lahti; [2012]
   Keywords : filter; interpolation; decimation; tree-structure; Nyquist; linear-phase;

   Abstract : The master thesis is based upon a new type of linear-phase Nyquist finitie impulse responseinterpolator and decimator implemented using a tree-structure. The tree-structure decreasesthe complexity, considerably, compared to the ordinary single-stage interpolator structure. READ MORE

4. 3. FPGA Implementation of an Interpolator for PWM applications

   University essay from Institutionen för systemteknik

   Author : Jasko Bajramovic; [2007]
   Keywords : interpolator; half band FIR filter; MCM; Altera;

   Abstract : In this thesis, a multirate realization of an interpolation operation is explored. As one of the requirements for proper functionality of the digital pulse-width modulator, a 16-bit digital input signal is to be upsampled 32 times. To obtain the required oversampling ratio, five separate interpolator stages were designed and implemented. READ MORE
