Operations Using DSP processor

In this experiment we performed certain Arithmetic Instructions using the code.We did Addition,Subtraction, Multiplication,And Logical Operations such as AND ,NOT ,shifting operations such as SHIFT left and right and rotation.Registers store the values of the result,Basic mathematical operations take the operands from the register.DSP processors have specially designed hardware to support arithmetic and logical operations by Multiply and Accumulate Unit.MLA unit

      Yes.The implementation was difficult and tedious

    It has a dedicated bit reversal unit to perform fast algorithms like FFT.

FIR filter design using the FSM approach.

In this the flow of the parameter calculation was kept the same as was for the window function.Nevertheless ,an added parameter called H(k) was calculated which o is the notation for DFT result.The length of this result was obtained from the Order of the filter which was given.Further omega was taken to be (2πk/N) where N was the order.One other ,slightly difficult task was plotting the realisation diagram.Ofcourse we didn't do this but the function was separated in its cascaded form for getting h(n) by sampling.The frequency sampling approach allows is to design the filter for both -std.frequency responses and arbitrary responses.Its applications include biomedical signal processing, compression etc. The main idea of the frequency sampling design method is that a desired frequency response can be approximated by sampling it of N evenly spaced points and then obtaining an interpolated frequency response that passes through the frequency sample.

Butterworth Filter Design

In this experiment we designed an IIR Filter namely Butterworth Filter.The Passband and Stop Band Attenuation were kept constant at 45db and 3db respectively.The code for the order and the normalised filter was typed according to the theory.BLT method was used for getting the exact transfer function.Further,the graph observed was minimally flat graph with no ripple in Pass band and Stop Band.Due to its maximum flat pass band nature it is used as anti-aliasing filter in data converter applications.

Chebyshev Filter Design

The aim of this experiment was to design a Chebyshev Filter.The formulae were completely different from those of Butterworth Filter.The flow followed was the same ,i.e the order and the normalised function was calculated first followed by the transfer function using BLT approach.Two types of Chebyshev Filters namely 1 and 2 were studied.The first one had ripple in Passband and the second one had ripple in Stopband.The order of the filter could be calculated from the graph by counting the number of ripples in either Stop Band or Pass Band which was interesting.It is used where the frequency content is more important than having a constant Amplitude.It is widely used in RF Applications because of its Steep Roll off.
