Two Input or Gate

This Trainer Consist of : 1. Regulated power supply of ± 12 V / 250 mA. 2. Variable 0 to ±5 V / 250 mA. 3. Sine wave oscillation of 1 KHz. 4. Digital Voltmeter of 0-20 V DC, LCD display, 3 ½ Digit. 5. Functional diagram of IC 741 is printed with 2 mm sockets. 6. One extra 8 pin IC Base with 2 mm sockets. 7. Potentiometer of 10K Ohms. 8. Required Resistance and Capacitances mounted on board. 9. Interconnection Leads and Manual to perform 15 experiments on IC741 e.g. inverting, non-inverting, summing, difference, multiplier, differentiator, integrator etc.

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.

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.

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.
