The correct answer is: A controller, essentially, is a comparator.<\/strong><\/p>\n A comparator is a device that compares two input signals and produces an output signal indicating which input is larger. It is a fundamental building block in many electronic circuits, and is used in a wide variety of applications, such as analog-to-digital converters, data acquisition systems, and control systems.<\/p>\n A sensor is a device that detects and responds to a physical stimulus such as light, heat, pressure, or sound. Sensors are used to measure physical quantities and convert them into electrical signals that can be read by a computer or other electronic device.<\/p>\n A clipper is a circuit that limits the amplitude of an input signal to a specified range. Clippers are used to protect circuits from overvoltage conditions, and to remove unwanted noise from signals.<\/p>\n An amplifier is a device that increases the power of an electrical signal. Amplifiers are used in a wide variety of applications, such as audio amplifiers, radio transmitters, and radar receivers.<\/p>\n","protected":false},"excerpt":{"rendered":" [amp_mcq option1=”sensor” option2=”clipper” option3=”comparator” option4=”amplifier” correct=”option1″]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[961],"tags":[],"class_list":["post-51384","post","type-post","status-publish","format-standard","hentry","category-electrical-control-systems","no-featured-image-padding"],"yoast_head":"\n
