Undoubtedly, frequency is one of the fundamental parameters for any electronic equipment. Frequency specifies the rate of oscillatory movements and vibrations. In electrical and electronics, frequency measures the rate of oscillatory movement of current flowing through a circuit. The international unit of frequency is Hertz that equals 1 cycle per second. Want to know how […]
Working of SWR Meters This article focuses on the concept of Standing Wave Ratio, its measurement using SWR meters, directional swr meter, Voltage Standing wave ratio (vswr), Swr bridge circuit, applications and problems with an SWR meter. SWR Meter IMAGE SOURCE SWR meters are used to measure and denote the standing wave ratio in a
What is a Wheatstone bridge? A Wheatstone bridge is an electrical circuit used to calculate an unknown resistance with the help of a bridge circuit. For this, the two legs of the bridge circuit are kept balanced and one leg of it includes the unknown resistance. The Wheatstone bridge principle is similar to the working of
