Wire harnesses are bundled assemblies of cables and connectors, that are used to transmit signals and power between components. If we could compare a satellite to the human body, the electrical harness would represent the blood vessels conveying the power and the nervous network transmitting the commands and sensor information …

Modern computers operate in a “noisy” electronic environment. They are surrounded by powerful electromagnetic interference (EMI) generated by radios, radar, microwave transmitters, other computers, and a wide assortment of electronic equipment. Electromagnetic Interference (EMI) is electromagnetic energy that disturbs, interrupts, obscures or degrades the effective performance of the electrical equipment. Electromagnetic …

Signals intelligence (SIGINT) is intelligence-gathering by interception of signals, whether communications between people (communications intelligence—abbreviated to COMINT) or from electronic signals not directly used in communication (electronic intelligence—abbreviated to ELINT). The abbreviation SIGINT – Signals Intelligence – stands for collecting and analyzing of information from radar- and radio-signals. Because …

Printed circuit boards (PCBs) are the foundational building block of most modern electronic devices on which all of the other electronic components are assembled onto. A circuit card is a thin, flat piece of dielectric material that has conductive paths or traces etched on it. These conductive circuits – usually …

Microwave networks consist of many ports. For example, in phased arrays, which are used in 5G wireless communication in base stations, we often have systems that can even have 100s or 1000s of ports, input-output ports. We need to come up with a concept to describe much more complex microwave …

A system, whose output can be managed, controlled or regulated by varying its input is called Control System. If we look around, we will find many control systems in our surroundings i.e. Refrigerator, Air Conditions, Washing Machines etc. An automatic speed control system, also called cruise control, works by …

Integrated circuits (ICs) are generally classified as digital (e.g. a microprocessor) or analog (e.g. an operational amplifier). Mixed-signal ICs are chips that contain both digital and analog circuits on a single semiconductor die. Mixed-signal ICs also process both analog and digital signals together. For example, an analog-to-digital converter is a …

Industrial control system (ICS) is a collective term used to describe different types of control systems and associated instrumentation, which include the devices, systems, networks, and controls used to operate and/or automate industrial processes. ICS are typically used in industries such as electric, water and wastewater, oil and natural gas, transportation, …
