In nodal analysis, we use KCL at each node to determine the node voltages. This is why we need to determine the branch currents, which can be a little difficult to read if a voltage source exists between...

Manual vs Automatic Switching Systems: A Comparison
Manual and automatic switching systems are two different methods of controlling the flow of data or signals through a network or system. Let's compare the two:Manual Switching System:In a manual switching...
Writing a Prime Number Program in Assembly Language
Prime numbers are a fascinating topic in mathematics and computer science. A prime number is a positive integer greater than 1 that has no positive integer divisors other than 1 and itself. In other...
Stray or Parasitic Capacitance in High Frequency Electronics Circuit
Capacitance means 'the ability to store the charge' and stray means 'not in the right place'. Therefore we can say that if capacitance is established anywhere (may be in a device or between devices)...
Earth is the Same, but Matter Exhibits Different Properties and Behaviors in Nature - Why?
According to modern electron theory, all matter is composed of three fundamental particles that are invisible to the naked eye: neutrons, protons, and electrons. An electron in copper is no different...
Performing Pulse Code Modulation and Demodulation using MATLAB Code
This is a MATLAB code for performing Pulse Code Modulation (PCM) on an analog signal. The code generates an analog signal, samples it, quantizes it, encodes it, and finally demodulates it back to obtain...
What do you mean by Constellation Diagrams in Communication Systems?
A constellation diagram is a graphical representation of a signal modulated by a digital modulation scheme such as quadrature amplitude modulation or phase-shift keying(QAM/QPSK). It shows the signal...
Sampling Theorem Statement
Sampling theorem state that the bandpass signal x(t) whose maximum bandwidth is 2w can be completely represented into and recovered from its samples, if it is sampled at the minimum rate of twice the...
Comparison of PCM, DM, and ADM: Which one is the best for digital communication?
When the analog signal is sampled, it can be quantized and encoded by any one of the following techniques-
i) Pulse code modulation (PCM)
...
Nodal Analysis of an Electric Circuit: Finding Node Voltages and Branch Currents
Find the node voltages and branch currents of the following electric circuit using nodal analysis:
According to the method of Nodal analysis, first of all we need to determine all the nodes of...
Understanding the Skin Effect in Transmission Lines
The skin effect is a phenomenon in which the AC current flowing through a conductor is concentrated near the surface of the conductor, and the deeper the current flows, the smaller the current density...
Types of Electronic Components: Active or Passive
An electronic/electrical component is any basic discrete device or physical entity in a system used to affect electrons or their associated fields. These can be of two types:Active elements: These are...
Security Risks in Satellite Communication: Is Intercepting Information Signals Possible?
It may be possible but difficult for individual . Many stipulations (conditions) are done so that no one will be able to do so.
1) Taking over the down link: One can take over the information sent...
Why are microwaves preferred for satellite communications?
Frequency of microwave bands extends from about one gigahertz to three hundred gigahertz. This large frequency bandwidth can carry huge information through different band.
Velocity = wavelength x frequency
From...
