Two Input or Gate

Instrumentation amplifier is a switched gain precision operation amplifier. This is used for precise and accurate, low noise differential signal acquisition. 4mm sockets are used for the input signal. It can be interfaced with a wide range of sensors. It can take small voltage changes from a sensor and make those changes large enough to be measured using CRO. It is not able to drive a low impedance load such as a loudspeaker or relay. The output can be read on CRO. Digital multimeter may also be used to read the output. With switched gain of 5 to 1000, it can handle signal inputs over a very wide range making it suitable for almost all applications.

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.

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.

Complete with Regulated power supply of + 5V/500 mA. Provided with 4 Logic input switches (bounceless) 4 LED Indicators (Buffered) Functional diagram of :- 1. 3 Input NAND – 6 No. 2. 4 Input NAND – 4 No. 3. 1 Input NOT Gates – 4 No. is printed on board. 4. 12 Interconnection Leads and User’s Manual is provided.
