Two Input or Gate

A common anode seven segment module is fitted on a board with 8 bit dip switch to control the each segment of seven segment LED display. The inputs A-D of a display driver are connected to the binary coded decimal (BCD) outputs from a decade counter. A network of logic gates inside the display driver makes its outputs a-g become high or low as appropriate to light the required segments a-g of a seven segment display. A resistor is required in series with each segment to protect the LEDs

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.

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.
