Mounted on transparent covered base for easy demonstration. Diagram and two sockets are provided for use with some circuit. Thermistor is mounted above the base to avoid the damage from heat.
Instrument is design to demonstrate the method to transmit signals via. Electromagnetic transmission. It is still used in radio system to transmit audio signal although it has lesser in popularity compared to FM (Frequency Modulation) due to its lower signal to noise ratio.
Technical Specification :-
1. I C based DC regulated Power Supply ±12 V / 500 mA.
2. Audio frequency 1 KHz / 0-2 Vpp for modulating signal 455 KHz / 2.5 Vpp approx. for Carrier Frequency.
Objective : To study Efficiency and Ripple factor in case of Half wave, Full wave and Bridge rectifier on application of load and filters.
Features : Instrument comprises of AC Power Supply, 3 meters to measure Output Voltage, Output Current and ripple factor on electronic AC Voltmeter, 4 PN Junction Diodes, Filter Circuit kit, load Resistances selectable using bandswitch and all important connections points at 4mm Sockets.
Optional Acc : Digital AC millivoltmeter.
Each module is housed in a plastic box 90 x 90 x 30 mm and is provided with a circuit diagram on the panel. It has necessary input and output sockets. The socket stacking system allows addition of as many modules as desired, designed to work on 6V D. C.
