The correct answer is: A. Graphic pen recorder<\/strong><\/p>\n A graphic pen recorder is a device that produces a paper record of an analog waveform. It is usually used to measure and record electrical signals, such as those produced by a heart monitor or an oscilloscope. The pen recorder consists of a moving pen that traces the waveform on a piece of paper. The paper is moved past the pen at a constant speed, and the pen is controlled by an electronic circuit that converts the analog signal into a series of electrical pulses. The pulses cause the pen to move up and down, creating a record of the waveform on the paper.<\/p>\n The other options are incorrect because:<\/p>\n [amp_mcq option1=”Graphic pen recorder” option2=”Electron microscope” option3=”X-Y recorder” option4=”Oscilloscope” 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":[740],"tags":[],"class_list":["post-55164","post","type-post","status-publish","format-standard","hentry","category-electronics-and-instrumentation","no-featured-image-padding"],"yoast_head":"\n\n
