In this chapter, we explain the Fourier series representation of continuous-time signals. The history of the trigonometric sum goes back to the Babylonians. First, Euler examined the vibrating string and discovered that the frequencies produced by the string were harmonics of each other. Following ...

Sensitivity analyses of continuous and discrete systems in the time and frequency domains The technique of sensitivity analysis is old and well known, but few modern papers include them, perhaps because of the subtle tricks and customizations th... WJ Karnavas,PJ Sanchez,AT Bahill - 《Systems ...
We offer a formal investigation of the measurement principle of time-of-flight 3-D cameras using correlation of amplitude-modulated continuous-wave signals. These sensors can provide both depth maps and IR intensity pictures simultaneously and in real time. We examine the theory of the data acquisi...

For analysis of continuous time LTI system Laplace transform is used. And for analysis of discrete time LTI system z transform is used. Z transform is mathematical tool used for conversion of time domain into frequency domain (z domain) and is a function of the complex valued variable Z. The...
time-frequency curves is presented.A general law for crossed item appearing is studied.In time-frequency plane,the images of signal items are smooth continuous curves,but the images of crossed items are pinto interference patterns.For a multicomponent signal,crossed items appear in midpoint set of...
This example shows how to use the continuous wavelet transform (CWT) to analyze modulated signals. Load a quadratic chirp signal. The signal's frequency begins at approximately 500 Hz at t = 0, decreases to 100 Hz at t=2, and increases back to 500 Hz at t=4. The sampling frequency is...
