Course Outcomes:
Upon successful completion of this course, a student will be able to…

1. Identify (and minimize) the sources of noise that occur in A-to-D conversion;
2. Compute the convolution operation and the correlation operation (both 1-D and 2-D);
3. Compute the Discrete Fourier Transform (and the Inverse DFT) and decompose a complex signal into its spectrum;
4. Convert between rectangular and polar coordinates, and describe the advantages of each;
5. Do common processing operations in either the time or the frequency domains;
6. Implement amplitude modulation and compression/expansion, and understand potential sources of error in each;
7. Design a FIR filter, either from scratch, or by combining existing filters;
8. Predict what the output of a filter will be;
9. Be able to convert between color systems;
10. Do point processing on images affecting color, brightness, etc.;
11. Do blurring and sharpening on images using 2-D convolution, and understand filter directionality;
12. Do statistical filtering on images;
13. Do 2-D translation, rotation, scaling, mirroring, and basic image warping;
14. Synthesize sounds from scratch, and from samples;
15. Implement mixing, amplitude modulation, companding, echos, reverb, pitch-shifting, and equalization of sounds;
16. Implement and understand the effects of audio filters;
17. Implement Huffman, LZW, RLE, delta modulation, transform, and sub-band coding;
18. Implement an adaptive playback buffer;
19. Write programs that capture and playback audio and images, use popular programs for image and audio processing, and use matlab to do image and audio processing.
