Page Shift Keying (PSK) Method is used to modulate digital signal at 9600 bps using 16 level. Find the line signals and speed (i.e. modulation rate).
Correct Answer: A
Question 575 Explanation:
Page Shift Keying (PSK) Method uses power of 2 number of bits.
2 level→ 21 → 1 bit
4 level → 22 → 2 bits
8 level → 23 → 3 bits
16 level → 24 → 4 bits
32 level → 25 → 5 bits
Given data,
— Digital Signal=9600bps
— 16 levels
— Baud rate=?
Step-1: Baud rate= Total digital signal / level bits
= 1600 / 4
= 2400 bauds
2 level→ 21 → 1 bit
4 level → 22 → 2 bits
8 level → 23 → 3 bits
16 level → 24 → 4 bits
32 level → 25 → 5 bits
Given data,
— Digital Signal=9600bps
— 16 levels
— Baud rate=?
Step-1: Baud rate= Total digital signal / level bits
= 1600 / 4
= 2400 bauds
2400 bauds
1200 bauds
4800 bauds
9600 bauds
