FIR FILTER DESIGN USING FREQUENCY SAMPLING METHOD

The aim was FIR Filter design using Frequency Sampling Method.
We designed the digital filter using frequency sampling method.
The input specifications were given as
For LPF / HPF filter Design :
(1) Pass band Attenuation (Ap) (2) Stop band Attenuation (As )
(3) Pass band Frequency (Fp) in Hz (4) Stop band Frequency (Fs) in Hz
(5) Sampling Frequency in Hz
 For BPF / BSF filter Design :
(1) Pass band Attenuation (Ap) (2) Stop band Attenuation (As )
(3) Pass band Frequency (Fp1, Fp2) in Hz (4) Stop band Frequency (Fs) in Hz
(5) Sampling Frequency in Hz       
In this experiment we observed that phase response will be same for low pass and high pass filter if the orders are kept same. We also verified the values of Ap and As.

DSP PROCESSOR: HARDWARE IMPLEMENTATION

The aim of this experiment was to perform operations using DSP Processor.  We learned programming using DSP Hardware. In this experiment, we took two, 4 point signal values performed addition, subtraction, multiplication and division using Processor. We also performed bitwise logical operations and shifting of signal values. After performing each of these operations we verified the register values and compared them with the values of these registers before the execution of these instructions. We observed the practical implementation of the processor and its instructions.

DESIGN OF BUTTERWORTH FILTER

The aim of this experiment was designing analog and digital Butterworth filter. We designed a digital filter from analog filter and studied the aliasing effect due to sampling in Impulse Invariant Method and the frequency warping effect in BLT Method. The Input Specifications were given as (1) Pass band Attenuation  (2) Stop band Attenuation  (3) Pass band Frequency (4) Stop band Frequency  (5) Sampling Frequency        We arrived at a conclusion that for both low pass and high pass filter, poles lie inside the unit circle. Hence both the filters are stable. But we also observed in the result that the values of Ap and As are not approximately same. Hence for better stability the order of the filter needs to be increased.
