What are the uses of multiplexer?

A multiplexer makes it possible for several input signals to share one device or resource, for example, one analog-to-digital converter or one communications transmission medium, instead of having one device per input signal. Multiplexers can also be used to implement Boolean functions of multiple variables.

What is the need of multiplexing in microprocessor?

A multiplexer is a system of multiple inputs and just one output to receive signals coming from multiple acquisition networks. The device transfers all input signals to a microprocessor, which receives and processes the data, transmits it to the output devices, and controls the system as a whole.

What is multiplexer and demultiplexer in microprocessor?

A multiplexer (Mux) is a combinational circuit that uses several data inputs to generate a single output. A demultiplexer (Demux) is also a combinational circuit that uses single input that can be directed throughout several outputs. Multiplexer includes several inputs and the single output.

What does a multiplexer do Mcq?

A multiplexer (or MUX) is a device that selects one of several analog or digital input signals and forwards the selected input into a single line, depending on the active select lines.

What are the purposes of using decoder and multiplexer?

A multiplexer and a decoder can be used together to allow sharing of a data transmission line by a number of signals. In the following diagram, the Control input consists of n wires, and there are 2n data inputs and outputs. The Control input determines which of the data inputs is connected to the transmission line.

Why a multiplexer is called a data selector?

Basic Multiplexing Switch In digital electronics, multiplexers are also known as data selectors because they can “select” each input line, are constructed from individual Analogue Switches encased in a single IC package as opposed to the “mechanical” type selectors such as normal conventional switches and relays.

What is the role of multiplexer and decoder?

The main function of multiplexer basically is to connect information from one point to another point through wires while on the other hand, decoders converts the outputs for several operations such as data collection and calculations.

What is a microprocessor used for?

A microprocessor is designed to perform arithmetic and logic operations that make use of small number-holding areas called registers. Typical microprocessor operations include adding, subtracting, comparing two numbers, and fetching numbers from one area to another.

What is a multiplexer Mcq?

a multiplexer is a device which converts many signals into one. Explanation: a multiplexer (or mux) is a device that selects one of several analog or digital input signals and forwards the selected input into a single line, depending on the active select lines.

What is the role of multiplexer when enable input is high Mcq?

What is the function of an enable input on a multiplexer chip? Explanation: Enable input is used to active the chip, when enable is high the chip works (ACTIVE), when enable is low the chip does not work (MEMORY).

What is the architecture of 8085 microprocessor?

The 8085 microprocessor is an 8-bit processor available as a 40-pin IC package and uses +5 V for power. It can run at a maximum frequency of 3 MHz. Its data bus width is 8-bit and address bus width is 16-bit, thus it can address 216= 64 KB of memory. The internal architecture of 8085 is shown is Fig. 2.

Why Intel 8085 has multiplexed data and address lines?

Similarly, Intel 8085 has multiplexed Data and Address lines to make the chip smaller, effective and cheaper as the programmer will only be using one at a time and providing an dedicated Address lines not only increases chip size but also cost and complexity of circuit. Hope you find it useful. Thank you for reading.

What is sequential execution in 8085 microprocessor?

In case of 8085 microprocessors, the execution of instructions is sequential. That is, no two instructions can be executed at the same instance or clock pulse. This means data loading and address loading always occurs at different clock pulses. It simplifies the hardware because now the bus can be time shared for address loading and data loading.

What is 8085 flag register in microprocessor?

8085 is a second generation 8 bit microprocessor and is the base for studying and using all the modern microprocessors available in the market. Flag register is the second most useful component in all the generations of microprocessor, the first one being the accumulator.
