Frequency Divider It called as Clock divider That circuit takes an input signal of a frequency and generates an output signal of a frequency Frequency is the number of occurrences of a repeating event per unit of time Create Frequency divider using JK Flip Flops A frequency divider can be constructed from J-K flip-flops by taking the output of one cell to the clock input of the next. The J and K inputs of each flip-flop are set to 1 to produce a toggle at each cycle of the clock input. For each two toggles of the first cell, a toggle is produced in the second cell, so its output is at half the frequency of the first. The output of the fourth cell is 1/16 the clock frequency. The same device is useful as a binary counte r Create & Simulate
Counters a counter is a device which stores (and sometimes displays) the number of times a particular event or process has occurred, often in relationship to a clock. The most common type is a sequential digital logic circuit with an input line called the clock and multiple output lines. The values on the output lines represent a number in the binary or BCD number system. Each pulse applied to the clock input increments or decrements the number in the counter. A counter circuit is usually constructed of a number of flip-flops connected in cascade. Counters are a very widely used component in digital circuits, and are manufactured as separate integrated circuits and also incorporated as parts of larger integrated circuits. There are 2 types 1) Synchronous 2) Asynchronous How to create Asynchronous...
What is the Combinational Circuit A combinational logic circuit is one in which the present state of the combination of the logic inputs decides the output . The term combination logic means combining two or more logic gates to form a required function where the output at a given time depends only on the input. In Combinational circuit as output does not depend on the time instant, no feedback is required for its next output generation. Combinational circuits do not required to have a memory. Examples of Combinational Circuits These are some examples of Combinational Circuits. half adders full adders encoders and decoders subtractors Multiplexer De-multiplexer P rocedure of Creating Combinational logic First read the problem and understand it specify number of inputs and outputs and label them Derive the truth table for each of the outputs based...
