The sensitivity of a microphone is usually expressed as the sound field strength in decibels (dB) relative to 1 V/Pa (Pa = N/m 2) or as the transfer factor in millivolts per pascal (mV/Pa) into an open circuit or into a 1 kiloohm load. [citation needed] The sensitivity of a loudspeaker is usually expressed as dB / 2.83 V RMS at 1 metre.
Signal amplification performs two important functions: increases the resolution of the input signal, and increases its signal-to-noise ratio. [ citation needed ] For example, the output of an electronic temperature sensor , which is probably in the millivolts range is probably too low for an analog-to-digital converter (ADC) to process directly.
If a voltage outside the power supply rails is applied to the input, internal ESD protection diodes turn on, causing large currents to flow and damage these parts. Specialised current-sense amplifiers, by contrast are designed so that, when powered from a low-voltage power rail such as V CC = 5 V and V EE = 0 V, they can withstand pin voltages ...
Since the controller parameters are typically matched to the process characteristics and the process may change, it is important that the controller parameters are chosen in such a way that the closed loop system is not sensitive to variations in process dynamics. Moreover, the sensitivity function is also important to analyse how disturbances ...
Shoulder buttons ("bumpers") and triggers on an Xbox 360 controller. Some common additions to the standard pad include shoulder buttons (also called "bumpers") and triggers placed along the edges of the pad (shoulder buttons are usually digital, i.e. merely on/off; while triggers are usually analog); centrally placed start, select, and home buttons [clarification needed], and an internal motor ...
This Xbox controller is comfortable and ergonomic, and features a 3.5mm stereo headset jack, just like the Xbox Core controller. The included 10-foot USB cable is detachable, making it easy to store.
A minimum detectable signal is a signal at the input of a system whose power allows it to be detected over the background electronic noise of the detector system. It can alternately be defined as a signal that produces a signal-to-noise ratio of a given value m at the output.
Its name comes from the information path in the system: process inputs (e.g., voltage applied to an electric motor) have an effect on the process outputs (e.g., speed or torque of the motor), which is measured with sensors and processed by the controller; the result (the control signal) is "fed back" as input to the process, closing the loop.
