Basic bulding block of sequential logic circuits is

The basic building block of sequential logic circuits is the Flip-Flop.

Step 1: Understanding Sequential Logic Circuits Sequential logic circuits are a type of digital circuit which are influenced not just by the present inputs, but also, by the history of inputs. In other words, sequential logic remembers past events.

Step 2: Identifying the Basic Building Block The basic building block of these circuits is the Flip-Flop.

Step 3: Understanding Flip-Flops A flip-flop is a circuit that has two stable states and can be used to store state information. This means it can be used to store binary data, making it a crucial component for computer memory.

Step 4: Types of Flip-Flops There are different types of flip-flops, each with its own characteristics and uses. These include the SR (Set-Reset), D (Data), JK, and T (Toggle) flip-flops.

So, in conclusion, the basic building block of sequential logic circuits is the Flip-Flop.
