The loads which operate with a large signal current to current are...
by Tarun Agarwal 6 years ago What is a Harmonic Oscillator : Block Diagram and Its Types The simple harmonic motion is invented by French Mathematician Baron Jean Baptiste Joseph Fourier in 1822. Edwin Armstrong (18th DEC 1890 to 1st FEB 1954) observed oscillations in 1992 in their experiments and Alexander Meissner (14th SEP...
by Tarun Agarwal 6 years ago What is a SSB Modulation and Its Applications The modulation like SSB or single-sideband modulation is extensively used in the radio spectrum of short wave or HF portion for radio communications in two ways. This communication uses SSB modulation, and the applications of this range...
by Tarun Agarwal 6 years ago Difference between Resistance and Resistivity The resistance and resistivity concept is one of the most fundamental as well as an essential part of the concept of current & electricity. The major difference between resistance and resistivity of the material is that the resistance...
