When considering graduate schools for a master's in Electrical Engineering with a specialization in signal processing, it's important to recognize that signal processing encompasses a wide range of topics, including communications, control theory, and media processing. The choice of school may depend on specific interests within signal processing, such as audio, video, speech, image processing, information theory, biomedical applications, or aerospace and defense. While top-tier institutions like Stanford and MIT are often mentioned, there are many other reputable programs that also offer strong curricula in these areas. Identifying personal academic and career goals can help narrow down the best options for graduate studies in this field.
