SR Latch using NAND Gate | NAND SR Latch | Digital Electronics

February 11, 2023 fjm1972

When making use of static gateways as foundation, one of the most basic lock is the straightforward SR lock, where S and also R represent set and reset. It can be created from a pair of cross-coupled NOR or NAND logic gates. The saved little bit is present on the result significant Q.
The inputs are typically marked S and also R for Set and Reset specifically. Since the NAND inputs should generally be reasoning 1 to prevent influencing the locking action, the inputs are thought about to be inverted in this circuit (or energetic low).

Introduction to Counters | Digital Electronics

December 5, 2022 fjm1972

Counters are made use of not just for counting but likewise for gauging frequency and also time; increment memory addresses. Counters are particularly designed concurrent sequential circuits, in which, the state of the counter amounts to the count kept in the circuit by the flip flops. Counters compute or keep in mind down the number that the number of times an occasion took place.
0:00 – Introduction
0:21 – Counter
3:56 – Find Mod value of the counter
9:38 – Find no. of Flip flops

Synchronous vs Asynchronous counter | Digital Electronics

December 4, 2022 fjm1972

Synchronous counter is the one in which all the flip flops are clocked simultaneously with the similar clock input. On the contrary, an asynchronous counter is a device in which all the flip flops that constitute that counter are clocked with different input signals at different instants of time.

September 16, 2022 fjm1972

Counters are used not only for counting but also for measuring frequency and time ; increment memory addresses . Counters are specially designed synchronous sequential circuits, in which , the state of the counter is equal to the count held in the circuit by the flip flops. Counters calculate or note down the number that how many times an event occurred.

Ring Counter | Synchronous Counters | Digital Electronics

August 15, 2022 fjm1972

A ring counter is a typical application of the Shift register. The ring counter is almost the same as the shift counter. The only change is that the output of the last flip-flop is connected to the input of the first flip-flop in the case of the ring counter but in the case of the shift resister it is taken as output. Except for this, all the other things are the same.
No. of states in Ring counter = No. of flip-flop used
The synchronous counter is a type of counter in which the clock signal is simultaneously provided to each flip-flop present in the counter circuit. More specifically, we can say that each flip-flop is triggered in synchronism with the clock input.

Introduction to Encoder and Decoder | Digital Electronics

August 15, 2022 fjm1972

Encoders are digital ICs used for encoding. By encoding, we mean generating a digital binary code for every input. An Encoder IC generally consists of an Enable pin which is usually set high to indicate the working. It consists of 2^n input lines and n output lines with each input line being represented by a code of zeros and ones which are reflected at the output lines.
Decoders are digital ICs which are used for decoding. In other words, the decoders decrypt or obtain the actual data from the received code, i.e. convert the binary input at its input to a form, which is reflected at its output. It consists of n input lines and 2^n output lines. A decoder can be used to obtain the required data from the code or can also be used for obtaining the parallel data from the serial data received.

SR Latch using NAND Gate | NAND SR Latch | Digital Electronics

July 26, 2022 fjm1972

When using static gates as building blocks, the most fundamental latch is the simple SR latch, where S and R stand for set and reset. It can be constructed from a pair of cross-coupled NOR or NAND logic gates. The stored bit is present on the output marked Q.
The inputs are generally designated S and R for Set and Reset respectively. Because the NAND inputs must normally be logic 1 to avoid affecting the latching action, the inputs are considered to be inverted in this circuit (or active low).
