### Day 45: Logical Circuits

Hello Dear Students,
Hope you all are doing good.

Today we will going to study about the logical circuits basic introduction.

Let's get started...

LOGICAL CIRCUITS - Basically logical gates connected hote hain, ek gate ki output doosre gate ki input hoti hai, then isko logical circuit kehte hain.
In digital systems, logical circuits are of 2 types-
1. Combinational Circuits
2. Sequential Circuits
1. COMBINATIONAL CIRCUITS
• In Combinational Circuits, the output is determined by the current input state only.
• Means, the output depends on inputs only, at a given point of time.
• Isme memory element ko consider nahi kiya jata.
• Combinational circuits ko design karne ke liye only Gates and Circulatory lines ko use kiya jata hai.
• It is easy to design.
• The speed is fast.
• It is less expensive.
• Combinational Circuits examples are-
2. Subtractors
3. Decoders
4. Encoders
5. Multiplexers
6. Demultiplexers

2. SEQUENTIAL CIRCUITS
• In Sequential Circuits, the output is determined by current input state along with memory elements.
• The memory elements store information of the previous state of the circuit.
• Means, the output depends on input as well as previous states of circuit(memory).
• Sequential circuits ko design karne ke liye gates, circulatory lines and memory elements ko use kiya jata hai.
• It is difficult to design.
• The speed is comparatively low from combinational circuits.
• These are expensive.
• Sequential Circuits examples are-
1. Flip-Flops
2. Registers
3. Counters

Next, we will discuss about these,
