1932-1236 elf study as well. It begins with a gentle introduction to the idea of abstraction by looking at numbers—the one highly abstract concept we use all the time. It then introduces some special functions that are useful for analyzing signals and systems. It then spends some time discussing some of the p

What is This Course About, a signal, a speech is a signal, as is a song, or a snarl. A picture is a signal, as is a movie. A strand of DNA is a signal, a protein is a signal, a hormone is most definitely a signal. Signals surround us so completely that we could if we wanted to classify the entirety of our world in terms of s

Complex Numbers,a, a negative number was considered, “absurd,” or “false,” or as late as the 19th century “imaginary.” Somebody who didn’t like negative numbers was the Egyptian (or Greek if you are talking to a Greek) mathematician Hero (or Heron) of Alexandria. Hero was looking for the volume of slices of a pyram

Classification of Systems,onkers. All around us we see systems, both natural and manufactured. Closest to us, our body is an incredibly complex system of systems with the different systems communicating with each other through chemical and electrical signals. Clearly, putting together the mathematical machinery required to h

Linearity, Time-Invariance, and the Role of the Impulse Response,unit impulse of a linear time-invariant system completely characterizes the system for both continuous time systems and discrete time systems. We will begin with discrete systems and then go through the process again with continuous systems.

Discrete Time Convolution,al construct, it is a roadmap for how a discrete system works. This becomes especially useful when designing or implementing systems in discrete time such as digital filters and others which you may need to implement in embedded systems.
