galvanizing process with varying the different types of Eco-friendly fluxes and conventional fluxes to study its effect on the corrosion performance & other physical properties of zinc coatings. Quality of this galvanized steel is characterized by AC impedance spectroscopy. Coating thickness was determine by coating thickness gauge while adhesively of coating were find out by bend test. Corrosion performances of coating was determined by potentio-dynamic test using Potentiostat Gammry Reference 600 & Salt

ABSTRACT Capacitance measurement is of immense importance in the field of electronics. An instrument that measures capacitance to accuracy better than 0.5% has been improvised and rendered auto-ranging by means of an 89c51 circuit. The principle is that of a “direct” or fundamental principle of the time constant of the component. For e.g.‚ the time taken to charge a capacitor to 50% of the applied voltage is given by 0.5 V = V (1- exp (-t/τ) ) The value of t is determined as 0.69314718τ. Knowing

A telephone‚ or phone‚ is a telecommunications device that permits two or more users to conduct a conversation when they are not in the same vicinity of each other to be heard directly. A telephone converts sound‚ typically and most efficiently the human voice‚ into electronic signals suitable for transmission via cables or other transmission media over long distances‚ and replays such signals simultaneously in audible form to its user. The wordtelephone has been adapted into the vocabulary of many

1. A 1.4M Hz carrier is modulated by a music signal that has a frequency components from 20 Hz to 10k Hz. Determine the range of frequencies generated for the upper and lower sidebands. Solution: Upper Side Band = 1‚ 400‚ 000 Hz + 20 Hz = 1‚400‚ 020 Hz Up to = 1‚ 400‚ 000 Hz + 10‚ 000 Hz = 1‚ 410‚ 000 Hz Lower Side Band = 1‚ 400‚ 000 Hz – 10‚ 000 Hz = 1‚ 390‚ 000 Hz Up to = 1‚ 400‚ 000 Hz – 20 Hz = 1‚ 399‚ 980 Hz 2.
