In aerospace applications, especially in space applications, size, weight, and reliability are critical parameters. If power is handled at low frequencies, the transformers and other energy storage elements occupy a huge amount of space. With switching converters that work at high switching frequencies...
Linear time complexity, often denoted as O(n), describes an algorithm whose execution time grows linearly with the size of the input data. It means that the time it takes to execute the algorithm is directly proportional to the number of elements being processed. Analyzing the time complexity ...
There are several materials and elements used to make semiconductor. The basic requirement is that the material should not be a very good conductor of electricity, nor should it be a very bad conductor of electricity. Its properties can be changed by adding or removing atoms / impurities. Semic...
In a non-contact temperature sensor, the element is not in direct contact with the thermal source (analogous to anon contact voltage tester or voltage pen). Non-contact temperature sensors use principle of convection for heat flow. Various temperature transducers that are generally used are describe...
With millions or billions of components on one single chip, it's not possible to position and connect each component individually. Dies are too small to solder and connect to. Instead, designers use a special-purpose programming language to create small circuit elements and combine them to progre...
Today signal conditioners include some of the required elements that make them useful for modern data acquisition systems. These elements are: Electrical isolation The right connectors for sensor connections Measurement range selection Signal filtering (e.g. anti-aliasing filtering) ...
There are many types of oscillators, but can broadly be classified into two main categories – Harmonic Oscillators (also known as Linear Oscillators) and Relaxation Oscillators. In a harmonic oscillator, the energy flow is always from the active components to the passive components and the frequenc...
Very strong clues about which elements of a signal are most essential to be preserved can be observed by a quick look at the specifications of the signal amplifiers (aka “signal conditioners”) used in today’s best DAQ systems. Here are the elements that are most often specified: Input Ra...
Apart from the four basic types of motor mentioned above, there are several types of special electrical motors. These include linear induction motors (LIM),hysteresis motors,Stepper motors, andServo motors. Each of these motors have special features that have been developed according to the needs ...
Aluminum has become a popular choice for PCBs in applications requiring enhanced thermal management. Let’s examine the properties that make aluminum an attractive option for thermally-demanding PCB designs. Properties of Aluminum AlloyThermal Conductivity (W/m·K)Main Alloying Elements ...
