Question No. 1
Consider a periodic signal which is decomposed into 10 sine waves with frequencies 300, 900, 1100, 500, 700, 800, 1300, 1200,600 and 400 Hz, what is the Bandwidth of this signal? Give your answer with complete calculations and proper unit in given table.
Question No. 2
Draw the NRZ-I encoding scheme for the following bit pattern:
Note: Assume that NRZ-I first signal starts with Positive polarity.
Best of Luck!

Question 1. What is the bandwidth?
Max frequency = 1300 Hz
Min Frequency = 300 Hz
Bandwidth = Max – Min
Bandwidth = 1300 – 300
Bandwidth = 1000 Hz
how could find unit?
Hz is unit?
yes, Unit of frequency is hertz (hz)
this is wrong. the first signal will be positive and u have to start the inverting of 1's after 1st second(time interval)
NO ANSWER 2 IS RIGHT BECAUSE THEY SAID START FROM POSITIVE POLARITY
Which one is right? Please explain..!
