Discrete-time and continuous-time signals
This post answers the question "What is the difference between continuous and discrete signal?" From a general point of view, signals are functions of…
Classification of signals
Classification of signals Classification of signals: Even and odd signals This post covers topic of classification of signals.The continuous-time and discrete-time electromagnetic signals are…
Electromechanics – main terms
Elelctromagnetic forces are used to produce mechanical effects that are considered in terms of electromechanics. The applications of electromechanics are fairly wide like in…
Transformers and their types
Transformers are most frequent nowadays in the magnetic structures that are in use in many devices. The ideal transformer is a device that sets…
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…
Discrete LTI systems
This post answers the question "What is discrete LTI system?". It is useful to consider discrete-time signals as a sequence of impulses. For example,…
Fourier function representation
This post covers topic of fourier representation of a function. Most signals are represented with a set of exponential functions, resulting in complex exponential…
Fourier transform for continuous-time functions
This post covers the topic of fourier transform for continuous signal. Let's consider a Fourier representation of aperiodic signals. Let’s also consider an aperiodic…
Fourier transform for discrete-time periodic function
Here we consider Fourier transform for discrete-time 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…
