Signals And Systems Course And Certification

What Are The Basics of Signals and Systems?

A signal is a representation of how one parameter alternates with another parameter. For example, a voltage varying over time in an electronic circuit, or brightness changing with distance in an image. A system is any method that produces an output signal in response to a signal that was used as an input. Consecutive systems input and output continuous signals, such as the ones found in analog electronics. Private systems input and output discrete signals, such as computer programs that handle the that are values stored in arrays.

Signals and systems are generally discussed without identifying the exact parameters that are being represented. This is the same as using x and y in algebra mathematics, without specifying a concrete meaning to the variables. This bring forth the fourth rule for naming signals. If a more descriptive name is not specified, the input signal to a discrete system is normally called x[n], while the output signal is called y[n]. For constant systems, the signals x(t) and y(t) are used.

There are many reasons for wanting to learn about a system. For example, you may want to design a system to remove the noise that is observed in an electrocardiogram, sharpen the out-of-focus in an image, or to remove echoes in an audio recording. In other cases, the system might have a deformity or an interfering effect that you need to describe or measure. For instance, when you speak into a phone, you suppose the other person would hear something that resembles your voice. Sadly, the input signal to a transmission line is scarcely identical to the output signal. If you know how the transmission line is modifying the signal, maybe you can work toward offering solutions for its effect. In other cases, the system may denote some physical process that you want to study or understand. Radar and sonar are very good examples of this. These methods work by comparing the signals that are transmitted and reflected to find out the characteristics of an object in a remote area. In the areas of system theory, the problem is to find the system that converts the transmitted signal into the received signal.

At first view, it may seem like an overwhelming job to understand all of the possible systems in the world. Luckily, most useful systems fall into a classification that is referred to as linear systems. This fact is very much important. Without the concept of linear systems, we would be required to explore the individual components of many systems that are unrelated. With this method, we can then focus alone on the traits of the linear system category as a whole.

This course is designed for students and all passionate learners, who are willing to learn signals and systems in simple and easy steps. This course will give you deep understanding of basic Signals and Systems concepts. After completing this course, you will be at an intermediate level of expertise from where you can take yourself to a higher level of expertise.
