About Course

MicrophoneCourse is introduction level and is on fundamentals of electronic communication, sampling, frequency spectrum, modulation and digital communication principles. An introduction to random variables and random processes will be made, noise and probability of error, energy and power spectra, measure of information and coding subjects will be studied. Here and here are the course and lab description documents respectively. We usually follow the textbook given in reading list, but it is strongly advised not to rely on a single resource.

Slides & Handouts

MicrophoneCourse slides are provided here in pdf format. Reading the slides before the class will help a lot understanding the subject. Course may not follow the order of slides listed here. Not all links are working, meaning that the slide does not exist (yet).
