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
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...
Decoder Decoder is a combinational circuit which have multiple inputs and multiple outputs circuit. It decodes n inputs into 2n outputs. Example: number of inputs are 2, number of outputs are 22 = 4. E is used to enable or disable the circuit. If E = 0, the circuit is disabled and if E = 1, the circuit is abled. How To Create & Simulate 2 to 4 Binary Decoder 2 to 4 Binary Decoder & Truth table
