Introduction




What are signals and systems?




A signal is a function that represents some physical quantity or phenomenon that varies with time, space, or any other independent variable. For example, sound waves, electrical currents, images, and temperature are all examples of signals. A system is a device or a process that performs some operation on a signal to produce another signal as an output. For example, a microphone, an amplifier, a filter, and a speaker are all examples of systems.


Signals and systems are essential concepts in many fields of engineering and science, such as communication, control, signal processing, image processing, biomedical engineering, robotics, etc. They help us to analyze, design, and optimize various systems that process information in different forms.

FAQs





  • What is the difference between continuous-time and discrete-time signals?



A continuous-time signal is a signal that is defined for all values of time. A discrete-time signal is a signal that is defined only for discrete values of time.


  • What is the difference between linear and nonlinear systems?



A linear system is a system that satisfies the properties of superposition and homogeneity. A nonlinear system is a system that does not satisfy these properties.


  • What is the difference between Fourier series and Fourier transform?



A Fourier series is a representation of a periodic signal as a sum of sinusoids with harmonically related frequencies. A Fourier transform is a representation of a non-periodic signal as an integral of sinusoids with continuous frequencies.


  • What is the difference between Laplace transform and Z-transform?



A Laplace transform is a representation of a continuous-time signal as a function of a complex variable s. A Z-transform is a representation of a discrete-time signal as a function of a complex variable z.


  • What is the difference between analog and digital filters?



An analog filter is a system that processes analog signals using analog components such as resistors, capacitors, inductors, etc. A digital filter is a system that processes digital signals using digital components such as microprocessors, memory, etc.
