Bridge Rectifier
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 electronic devices require direct current, so bridge rectifiers are used inside the power supplies of almost all electronic equipment. For an easy understanding of the internal circuitry, the circuit diagram is printed on the box.

Emitting Diode (LED’s)
The bridge rectifier is designed with four LED’s internally arranged in a bridge pattern fitted inside a plastic moulded case. Two LED’s are red and two LED’s are green. This device is used to demonstrate the functioning of a bridge rectifier, i.e., to convert alternating current (AC) into direct current (DC). Two yellow sockets are used for AC input. Two sockets, one red, and one black are used for DC output. For the easy understanding of the internal circuitry, the circuit diagram is printed on the box.

Analog to Digital Converter
The ADC unit converts an analog signal to a digital signal. When a variable voltage is applied to the input terminals it is converted into a digital output. Therefore, a 3-volt input will correspond to binary 11, and 7 volts will correspond to binary 111. A low-frequency AC input signal can be converted into a changing digital value. Use on its own or combined with the DAC to decode back into a stepped analog voltage.

Numerical System
This panel is used to demonstrate the number systems such as binary, decimal, and hexadecimal numbers. Toggle switches are 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. Operates on 220V.

Instrumentation Amplifier
An instrumentation amplifier is a switched gain precision operational 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. A digital multimeter may also be used to read the output. With the switched gain of 5 to 1000, it can handle signal inputs over a very wide range making it suitable for almost all applications.
