This melody generator can generatevarious English and Hinditunes as also instrumental effects.Various modes of melodies canbe selected through DIP switches.Other advantages are high volume andvolume control.IC UM3481A is a 16-pin multiinstrumentmelody generator. It isa mask-ROM-programmed IC designedto play the melody accordingto the programmed data. Its inbuiltpreamplifier provides a simple interfaceto the driver circuit. The IC canbe replaced with other UM348XXXseries, WR630173 or WE4822 melodygenerator ICs. A WR630173 pre ....etc

ABSTRACT

This paper focuses on a shunt active filter based on the detection of harmonic voltages at the point of installation. The objective of the active filter is to attenuate harmonic propagation resulting from series/parallel resonance between capacitors for power factor correction and line inductors in a power distribution line. The active filter acts as a low resistor to the external circuit for harmonic frequencies, and it is installed on the end bus of the power distribution line, just like a 50 O terminator installed on the end ter ....etc

Today, the situation on low-voltage AC systems has become a serious concern.The quality of electrical power in commercial and industrial installations is undeniably decreasing. In addition to external disturbances, such as outages, sags and spikes due to switching and atmospheric phenomena, there are inherent, internal causes specific to each site and resulting from the combined use of linear and non-linear loads.Untimely tripping of protection devices, harmonic overloads, high levels of voltage and current distortion, temperature rise in condu ....etc

ABSTRACT.
The ultrasonic testing of concrete structures has posed many problems. Conventional methods such as pulse echo and pitch catch are of limited use due to its composition, aggregates will cause scattering and multiple reflections. Alternative ultrasonic methods have been recently investigated that examine the shape of the waveform as it traverses through a complex material, the idea being not to located a single defect but to determine the overall mechanical properties within a certain region. In damaged materials, particularly ones ....etc
