## Signals and systems: The definition and characterising of signals

From a general point of view, signals are functions of one or several independent variables. There two types of signals – descrete-time and continuous-time…

## Signals and Systems: Types of signals

Types of signals. Even and odd signals: The continuous-time and discrete-time signals are called even if they are identical to their counterparts on the…

## Electromechanics: Theoretical basis

In the previous chapters we learned the operating principles of electric and magnetic fields. Elelctromagnetic forces are used to produce mechanical effects in the…

## Electromechanics: Linear Variable Differential Transformer (LVDT)

A Linear Variable Differential Transformer (LVDT) is a displacement transducer, used to measure displacement, based on the effect of the mutual inductances. It is…

## Signals and Systems: Discrete LTI systems

It is useful to consider discrete-time signals as a sequence of impulses. For example, a discrete-time signal is on show in Figure 1. Figure…

## Signals and Systems: Fourier function representation

Most signals are represented with a set of exponential functions, resulting in complex exponential functions. If these functions are affected with exponential external impact,…

## Signals and Systems: Fourier transformation for continuous-time functions

Let's consider a Fourier representation of aperiodic signals. Let’s also consider an aperiodic signal as the piece of the periodic signal within a period,…

## Signals and Systems: The Fourier transformation of discrete-time of periodic function

Let's consider the discrete-time Fourier-representation of a function fn=1N∑-∞∞anejn2πnK, where an=1N∑-∞∞F(jw)e-jn2πNk and F(jw)=∑xne-jn2πNk-∞∞. The pair of equations that are called the Fourier pair for discrete-time…

## Signals and Systems: LTI systems and their properties

Linear-time invariant systems, that were partially discussed before, play an important role in describing signals. Generally speaking, any process can be described with the…
