A CMOS (Complementary Metal-oxide Semiconductor) inverter is a device that produces logic functions and is the primary component of all integrated circuits. A CMOS inverter is a field-effect transistor that is composed of a metal gate that lies on top of an insulating layer of oxygen, which lies on top of a semiconductor. CMOS inverters …
GPS stands for Global Positioning System. It refers to a system of satellites that constantly transmit a signal, and a GPS terminal that picks up those signals and calculates its position on Earth by measuring the distance between itself and two or more GPS satellites (by measuring the time it takes to receive the signals). …
A breadboard is a thin rectangular piece of insulating material used to hold electronic components when making circuit prototypes. They have many rows and columns of conductive points for inserting component terminals and jumper wires. The original breadboards were just wooden boards, presumably used to cut bread on, but the modern versions have plastic cases …
Pulse Width Modulation, abbreviated as PWM, is a method of transmitting information on a series of pulses. The data that is being transmitted is encoded on the width of these pulses to control the amount of power being sent to a load. In other words, pulse width modulation is a modulation technique for generating variable …
Four digit security codes protect Kenwood car stereos from theft. If a thief steals a Kenwood car stereo, he/she will not be able to use the stereo until the secret four digit security code is entered. Unfortunately, many legitimate owners are also locked out of their Kenwood car stereos due to these security codes. This …
The SMA (SubMiniature Type A) connector is a type of the radio frequency connector developed in the 1960s to make it easier to connect coaxial cables. Using a screw-type design instead of the common ‘push-pull’ system, the SMA connector allows for a quick connection; and can be used in both alternating and direct current applications. …
Linear amplifiers are electronic circuits that have an output that is proportional to the input of the device while providing additional power to the load. A linear amplifier is normally a variant of a radio-frequency (RF) power amplifier and is used frequently in amateur radio and in laboratory and commercial audio equipment with an output …
Azimuth is a measurement at an angle used in the spherical coordinate system. To find a point of interest, the observer creates a vector that is then projected in a perpendicular fashion onto a reference plane. The resulting angle between the projected vector and the reference vector located on the reference plane is the azimuth. …
In the modern world of data and information, computer systems need circuits that are able to process and transfer that information. Because of this, a great deal of resources and innovation go into creating more advanced circuitry in order to increase data transfer rates and make computer systems smaller. This article will demonstrate how integrated …
The Ku band (Kurtz-under band) is primarily used for satellite communications, particularly for editing and broadcasting satellite television. This band is split into multiple segments broken down into geographical regions, as the ITU (International Telecommunication Union) determines. The Ku band is a portion of the electromagnetic spectrum in the microwave range of frequencies ranging from …
