Introduction A PA system that is installed correctly and operates at its optimum level will allow a sound signal to travel from one or more microphones to a mixing console. At the mixing console all signals will be mixed together in the right balance and levels and sent out to an amplifier. The signals are then converted into much larger signals and sent to the speakers creating sound waves for the audience to hear. (Fry‚ 2005) The aim of this report is to analyse by way of reference books

BRAINPORT VISION DEVICE By D.KALAIVANI R.PARVATHI DEVI ABSTRACT “BRAINPORT DEVICE” The device which sends visual input through tongue in much the same way that seeing individuals receive visual input through the eyes is called the “Brainport Vision Device”. BrainPort could provide vision-impaired people with limited forms of sight. To produce tactile vision‚ BrainPort uses a camera to capture visual data. The optical information

each time‚ the unknown resistance was approximately equal to the Ohm’s of the resistor‚ therefore confirming Ohm’s Law. An ammeter is connected in series because its purpose is to measure the current in the circuit‚ and since it is a low impedance device‚ connecting it in series would cause a short circuit‚ damaging the ammeter. Whereas the voltmeters purpose is to measure the electrical potential difference between two points in the circuit. The potential difference

The relationships between plant reproduction and human reproduction are that they both create an egg. There are feminine and masculine parts wanted in both progressions. Both produce descendants by sexual reproduction. The change among plant reproduction and human reproduction include that in pinnacle plants you have to plant the seed before it will develop into whatsoever‚ and in human reproduction you do not have to plant the seed it take a long procedure. Flowering plants create many more offspring
