Question

design, implementation and study of all the properties of 7-length and 15-length pn sequences using shift register.​

Answer 1

Answer:

Explanation:

Pseudo-Noise (PN) sequences are commonly used to generate noise that is approximately "white".

It has applications in scrambling, cryptography, and spread-spectrum communications. It is also commonly

referred to as the Pseudo-Random Binary Sequence (PRBS). These are very widely used in communication

standards these days. The qualifier "pseudo" implies that the sequence is not truly random. Actually, it is

periodic with a (possibly large) period, and exhibits some characteristics of a random white sequence

within that period. PN sequences are generated by Linear Feedback Shift Registers (LFSR), as shown in the

following figure:
