Static Error

Definition: A static error is defined as the difference between the measured value and the true value of the quantity. The true value is the exact value of the measurement which is impossible to obtain. Hence the approximate true value of the measurement should be taken into consideration. The accuracy is the most important characteristic …

Time Base Generator

Definition: The generator which is used for generating the linear variable voltage concerning time is known as the time base generator. These waves are used in cathode ray tube for deflecting the beam in a horizontal direction. The time base generator is also used in a radar system for determining the range of the target. The oscilloscope …

Measurement Error

Definition: The measurement error is defined as the difference between the true or actual value and the measured value. The true value is the average of the infinite number of measurements, and the measured value is the precise value. Types of Errors in Measurement The error may arise from the different source and are usually classified …

Null Type Instrument

Definition: An instrument in which zero or null indication determines the magnitude of measured quantity such type of instrument is called a null type instrument. It uses a null detector which indicating the null condition when the measured quantity and the opposite quantity are same. Such type of instrument has high accuracy and also it …

Accuracy & Precision

Accuracy Definition: Accuracy is the ability of the instrument to measure the accurate value. In other words, it is the closeness of the measured value to a standard or true value. The accuracy can be obtained by taking the small readings. The small reading reduces the error of the calculation. The accuracy of the system is classified …

Forward Bias p n Junction

A p n junction is said to be operating under the biasing condition if it is connected across an electric supply. The potential difference across the p n junction can be applied in two ways, namely Forward Biasing and Reverse Biasing. When the positive terminal of a DC source or battery is connected to p-type, …
