designed to explore the comparative effectiveness of transmitter of knowledge model and inductive inquiry model on students’ academic achievement. The main objectives of the study were to expose each of the two experimental groups to the transmitter of knowledge model and inductive inquiry model respectively and to compare the effectiveness of these models in the teaching of Social Studies. The pretest posttest control group experimental design was chosen for the experiment. It was hypothesized that

COOLING TECHNIQUES IN TRANSMITTER Introduction In modern A.M. transmitters power valves are used in the PA and modulator stages‚ which are condensed vapour cooled ceramic tetrodes. In the old generation transmittes‚ triodes are used in the PA‚ modulator and exciter stages. Both the tetrodes and triodes tubes are capable of being operated at high voltages (11 kV DC) and large anode current of the order of 50 Amps. They also draw large filament current of about 620 Anps at 24 volt CQK-350

LED and Laser Transmitters LED Transmitter Light - emitting diode (LED) is a standard light source that carries low speed signals at short distances. LED light source is an all plastic fiber that transmits visible light. LED put out lower power and a bigger output pattern than laser light sources. LEDs have less bandwidth and are limiting to operate up to about 250Mhz or about 200Mbs. LED light sources do not contain hazardous material and last longer‚ about 10‚000 hours. Bulbs generate less heat
