as referenced in APPENDIX B to carry out the drive reaction, a greatness reaction and stage reaction of the tried IIR channel. The executed chart of a greatness reaction, stage reaction, shafts/zeros plot, motivation reaction for the given coefficients are displayed underneath separately. greatness reaction e Phase Response Poles and Zeros Plot Impulse Response The figure beneath shows the channel data of the planned IIR channel. Channel Information From the figure, the IIR channel is a low pass channel which is planned by Direct-structure II translated structure, utilizing a channel request of 3. The numerator coefficient is bk, which are the zeros and the denominator coefficient is ak , which are the posts of the channel. The planned IIR channel is in stable condition, so the shafts and zeros exist in the solidarity. The examining recurrence is set as 96KHz. At first the exchange capability of the channel H(z) is given in the simple structure. Then it is changed from S-area to Z-area to plan the channel. Plan OF OTHER IIR FILTER: MATLAB FDAtool is utilized to plan a channel. New coefficients are imported in the channel plan and examination device. Here the construction of the channel configuration is Direct structure I change. The examining recurrence is given as 96KHz in a similar device. Presently the channel configuration will be created. In the event that the plan is found as shaky, the change ought to be made in shafts and zeros. By altering the place of shafts and zeros in the plot, and by adding more posts/zeros inside the solidarity, the plan of the channel can become steady. This adjustment ought to be finished in posts/zeros supervisor. Then the 16 bit new coefficients will be produced in the objective menu as displayed in APPENDIX C. The new plot of a greatness reaction, motivation reaction, stage reaction, and posts/zeros are displayed underneath individually.

From the code, the info tests x[ ], and yield tests y[ ], holds the worth if (N+1) tests , which are characterized as short. That is the examples are separated by 2^15, so the flood calculation of the mistake brought about by fixed point engineering in the DSK board can be forestalled. The result yn is characterized as number. From the record IIR_Coeffs.cof, b[4] and a[4] holds the cluster worth of the coefficients. The examining recurrence of 96KHz is given in the code as Uint32 fs=DSK6416_AIC23_FREQ_96KHZ. The bit by bit course of the planned code is made sense of underneath. ‘ Initially the size of the coefficients b[k], a[k] and the info test x[k] are characterized as short. With the goal that the length of the vectors are 16 pieces. ‘ The result esteem yn is characterized as a whole number. ‘ we characterized the underlying worth of yn as nothing. ‘ x[0] will take the information tests. ‘ Now the circle counter beginnings the course of computation by the recipe of the channel structure as referenced in the code. ‘ The determined worth is put away in yn. ‘ When the following circle begins, the result tests y[k] will get its worth from yn and begins the computation. ‘ The information cradle will move down after each circle to get the worth into the memory. Here the last worth of the cluster will be erased, it will have no space in the memory.

‘ Finally the result tests are scaled by output_sample() capability. Principal CHALLENGES OF IMPLEMENTING IIR FILTER FOR C6416: ‘ The channel configuration ought to be checked whether it is steady or shaky. Since, in such a case that it is in an unsteady state
