Two Input Ex-or Gate

Bridge Rectifier is made of four diodes connected in a bridge circuit. It is housed in a plastic moulded box. This bridge rectifier converts alternating current (AC) into direct current (DC). It provides the same output polarity for either input polarity. All the electronic devices require direct current, so bridge rectifiers are used inside the power supplies of almost all electronic equipment. For the easy understanding of the internal circuitry, the circuit diagram is printed on the box.

This panel is used to demonstrate the number systems such as binary, decimal and hexadecimal numbers. Toggle switches used to activate the displays showing the particular number entered. Input may be entered either as decimal or binary numbers with a toggle switch for mode selection. Decimal numbers are shown on a three digit seven segment LED display. 12 V / 2 A DC adaptor is required to operate it.

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.
