Logarithmic amplifiers correct input signal shifts by converting them to a constant output voltage. They are used in electrical circuits, medical devices, video circuits, fiber optics, and wireless devices. Advances in technology have made them more efficient and there are now three types: log DC, baseband, and demodulating. Each type has its own specific usage […]
Tuned amplifiers amplify specific electrical signals while blocking others. They are used in radios, TVs, and other communication equipment, as well as in aircraft, sound systems, and scientific instruments. They use band-pass filtering to allow only specific frequencies to pass through. They can have adjustable or fixed filters and amplifiers, and are found in nearly […]
A voltage amplifier increases the voltage output higher than the input voltage, while a power amplifier creates a more powerful output. A voltage booster is used to transmit higher voltage across longer wires. Voltage amplifiers increase power passing through a circuit to achieve a desired result and are not suited for powering devices such as […]
Load AMP is the demand an electrical circuit places on a power source. Batteries are rated to handle a specific range of AMP usage, while fuses and circuit breakers regulate the current sent to a device. Circuit breakers are preferred as they automatically break the circuit to prevent damage to the device or hardware. Load […]
Amps measure current, volts measure the strength of the flow, and watts are the total power released by a circuit per second. Ohms measure resistance. Understanding these terms is important for electrical work and evaluating electric bills. Amps, volts, and watts are all ways to measure different aspects of electricity. An ampere, or amp (A […]
A chopper amplifier transforms DC signals into AC currents to increase signal gain without introducing noise or instability. Chopper circuits interrupt and manipulate signals, and are found in various devices. Chopper amplifiers are used in high-end electronic signal equipment and heavy machinery, and are commonly found in hall probes used to measure changes in magnetic […]
A summing amplifier allows multiple signals to be added together while keeping each source separate. It is commonly used in audio mixers and signal conversion devices, and can handle both AC and DC currents. A summing amplifier is an electrical circuit layout that allows more than one signal to be added, creating a sum of […]
A bipolar amplifier outputs multiple signals based on the polarity of the input signal and adds gain while minimizing noise. Its design reduces noise and impedance matching is used to reduce noise generated by circuit components. Bipolar amplifiers are advantageous in reducing noise and are often used in broadcasting. A bipolar amplifier is a signal […]
Different types of computer audio amplifiers are available for gamers, movie buffs, and musicians. Surround sound systems are ideal for gamers and movie buffs, while musicians prefer audio interfaces with at least one audio input. Headphone amplifiers are suitable for sending audio to multiple pairs of headphones. It is important to ensure compatibility with your […]
An inverting amplifier reverses current flow to produce more power. It can shift the phase of waves and increase current output. It uses negative feedback and can be simple or complex. It is used in plasma arc cutting and welding equipment and can provide a low-cost alternative to other electrical devices. An inverting amplifier is […]
AMP sockets and plugs are plastic connectors used to join electrical cables. They consist of male and female parts with one to 12 or more separate connection points. The connectors are made of durable plastic and have locking tabs molded into them, ensuring a secure connection. AMP plug sets are available in a variety of […]
Isolation amplifiers protect delicate computer components from electrical power fluctuations. They block unwanted electrical activity and allow necessary activity to pass. They are commonly used to keep electrical and data input systems separate and to protect potentially hazardous environments. They also keep two components of one system separate and protected from unwanted electrical surges in […]
EEG measures electrical activity in the brain via electrodes on the scalp. The signals are amplified and recorded as brainwaves, which can be grouped into different frequencies. EEGs are used to record brain activity during different behaviors and to measure epileptic activity. Electroencephalography (EEG) is the measurement of electrical activity in the brain. The measurement […]
