Programmable Logic Devices (PLDs) can be programmed to implement various logic functions, including those required for driving a 7-segment decoder. A 7-segment decoder takes binary input and activates specific segments to display corresponding decimal digits. By configuring a PLD, you can create the necessary logic circuits that translate binary inputs into the appropriate outputs for the segments of the display. This programmable nature allows for flexibility in design and the ability to easily modify functionality as needed.

Programmable Logic Devices (PLDs) can be used to create custom logic circuits, including those that drive 7-segment displays. A 7-segment decoder takes binary input and activates the appropriate segments of the display to represent decimal digits. By programming a PLD, you can implement the logic required for the decoder, allowing for flexible design and easy modifications. This connection enables the display of numerical values based on varying input conditions.
We cannot connect the 74ls138 straight with a seven segment display; for that we need a 7447(7 segment driver).
A: A BCD code must be decoded to provide a seven digit output to the 7 bars display that is the only way to see the binary number visually.
To connect a common anode 7-segment display, you would typically connect the common anode pin to a positive voltage source and the individual segment pins to current-limiting resistors connected to the microcontroller output pins. When you provide a LOW signal to a segment pin, it will turn on that segment.
Decoding is necessary in applications such as data multiplexing, 7 segment display and memory address decoding.

Certainly not. The 74LS48 is a BCD to 7 segment decoder, and the CD40106 is a hex schmitt trigger inverter. A 7 segment display is the type of numeric display that consists of seven bars that form an 8 when all of them are lit. The LS48 takes a 4 bit BCD word and figures out which bars to light up.
To draw a circuit diagram for a digital clock using the 74LS293 IC, start by using the 74LS293 as a decade counter for counting seconds. Connect the clock input to a timing source, such as a 1 Hz oscillator, to increment the count every second. Additionally, connect the outputs of the 74LS293 to a display driver such as a 7-segment display decoder (e.g., 74LS47) to visualize the time. Ensure to incorporate reset circuitry and any necessary components like resistors and capacitors for proper operation.
