= 1.5 kHz (obtained from the instructor, every students should have a unique value)

The main purpose of the assignment is to demonstrate understanding and critical evaluation of digital processing techniques for a real-world problem. The block diagram of the DSP system to be simulated using Matlab code in this coursework is given in Figure 1a. Your task is to generate a sum of discrete-time sinusoidal signals with 1 kHz, and 4 kHz (with a peak-to-peak amplitude of 0.1 for each signals), sampled at a sampling rate of 64 ksamples/s. Then, add a noise to corrupt the signals. The noise signal can be created using Matlab code and the source type is Additive White Gaussian Noise with variance 0.05. Analyse the corrupted signal and create a filter specification to recover the signal from these signals. Design a filter using FDAtool and apply the filter to obtain the signal from the corrupted signal. Ideally, the output of the digital filter should be Sine Wave, as shown in Figure 1a.

a) You need have
‘Design Justification’ in the report. In order to design high-quality signal processing techniques in FDAtools, you should understand the structure and the specifications or parameters of the digital filter through textbooks, Matlab help files and other resources. Furthermore, you will need to gain enough knowledge of different filter types to be able to choose suitable blocks and specify critical points in the design. You must explain and justify your design choices (including FDAtool parameters and Matlab code) in detail with the aid of diagrams or mathematic equations. You need to include the screen shot of FDAtools in the report also. You also need to show the zero/pole diagram and comment on how are the zero/pole influence the filter.
