Frequency Modulation Recording: When a more accurate response to dc voltages is required, an Frequency Modulation Recording system is generally used. In this FM system, the input signal is used to frequency modulate a carrier,…
Magnetic Tape Recorder Working Principle: The major advantage of using a Magnetic Tape Recorder Working Principle is that once the data is recorded, it can be replayed an almost indefinite number of times. The recording…
XY Recorder Working: XY Recorder Working - In most research fields, it is often convenient to plot the instantaneous relationship between two variables [Y = f(x)], rather than to plot each variable separately as a…
Circular Chart Recorder Working Principle: Circular Chart Recorder Working Principle - As the name implies, the data is recorded on a flat circular chart. The basic assembly of a single pen circular chart recorder is…
Null Type Recorder: These Null Type Recorder Working Principle of self-balancing or null conditions. When an input is given to the measuring circuit of the recorder from a sensor or transducer, it upsets the balance of…
Galvanometer Type Recorder: The D'Arsonval movement used in moving coil indicating instruments can also provide the movement in a Galvanometer Type Recorder. The D'Arsonval movement consists of a moving coil placed in a strong magnetic…
Strip Chart Recorder Working Principle: Strip Chart Recorder Working Principle are those in which data is recorded on a continuous roll of chart paper moving at a constant speed. The recorder records the variation of…
Definition of Recorder: Definition of Recorder - A recorder is a measuring instrument that displays a time-varying signal in a form easy to examine, even after the original signal has ceased to exist. Recorders generally provide…
Detectors Types: The Detectors Types are as follows For low frequency, the most convenient detector is the vibration galvanometer. For ordinary laboratory work at frequencies up to a few 100 Hz, the moving coil type of…
Wagner Ground Connection: Wagner Ground Connection - When performing measurements at high frequency, stray capacitances between the various bridge elements and ground, and between the bridge arms themselves, become significant. This introduces an error in…
