The pulse oximeter is a medical device, used for measuring non-invasive blood oxygen saturation. An electrical engineer named Takuo Aoyagi invented it at Nihon Kohden in 1972. After that, the first pulse oximeter was launched in 1973. While...
An adder is a type of digital circuit in digital electronics that is used to perform addition operations. Even the operation of multiplication mainly depends on the sequence of this operation. So, these can be implemented simply in different...
An antenna is an aerial or metallic structure that converts electric current into EM (electromagnetic) waves. These are mainly used for transmitting & receiving non-ionizing electromagnetic fields, which comprise microwaves, radio waves,...
The Brent–Kung adder was proposed in 1982 by Hsiang Te Kung & Richard Peirce Brent. It is a Parallel Prefix adder or tree adder which is used widely in Digital Design due to its flexibility. Parallel Prefix Adders can be built in...
One of the main applications of op-amp is the summing amplifier or adder. When the op-amp’s input impedance is huge, above one input signal is provided to the inverting amplifier to add the given signal at the output, known as the summing...
The bandpass filter allows the signals to supply between two particular frequencies, even though separates these signals at other frequencies. These types of bandpass filters are available in various types; some of the bandpass filter design...
A motor starter is an electrical device used to control an electric motor in various applications by controlling the electrical power to start, stop, protect, and reverse the electric motor. This device includes two essential components...
Bode plots are fundamental tools in control systems and signal processing, offering a graphical representation of a system’s frequency response. Named after engineer Hendrik Wade Bode, these plots consist of two separate graphs: one...
Vehicle manufacturers around the world have been forced to reduce exhaust emissions. This applies to both petrol & diesel engines with a better focus on diesel because of the higher range of NOX pollutants they produce into the environment....
A high pass filter is an electronic filter that allows signals with a higher frequency than a certain cut-off frequency & attenuates signals by lower frequencies than that cut-off frequency. This filter is inverse to the low pass filter...
