The scenario
Design a 4-bit LFSR using D flip-flops for pseudo-random sequence generation.
What is in this drawing
Read the decisions behind it.
01
Select polynomial x^4 + x + 1 for maximal length
02
Use D flip-flops for synchronous shifting
03
Implement XOR feedback from outputs Q3 and Q0
Use in applications requiring pseudo-random binary sequences, such as test pattern generation or scrambling in communication systems.
