Sequence of Message Exchange

Q1. The guest passes the desire for a Pizza to the host. On receiving the
request, host starts looking up for address and number of the Pizza shop. On
finding the number , the hosts makes a telephone call to the listed number.
The telephone on other end notifies the Pizza Clerk to check Telephone. This
connects the Host with the clerk. Host places order for Pizza and mentions
his address. Clerk forwards the request to the cook so he can prepare the
dish. Once dish is prepared, the order is packed and parceled to the host
address as informed to the clerk earlier. The Pizza reaches hosts address by
delivery van.

Q2.
This process shows the sequence of message exchange between Two PM’s
who cannot understand each other’s language but Translators help them
communicate with each other using a third common language. Any
French PM

Telephone

conversation from French PM is translated to English and forwarded to
Chinese translator over Telephone. The Chinese translator receives the
message and translates it from English to Chinese and apprises the PM with
the message in Chinese. Vice versa happens when Chinese PM wants to send
a reply or a message to the French PM.
Q3 .
a. Amplitude : 15 ; Time period = 3 ; Frequency = 1/3 ; Phase =0
b. Amplitude : 4; Time period = 7 ; Frequency = 1/7 ; Phase =0
c. Amplitude : 8; Time period = 3 ; Frequency = 1/3 ; Phase =90
Q4. Equation for waveform A Sin (2ℿ (f)t + θ)
10 Sin(2 ℿ(100) t)

Amplitude = 10. ; Frequency = 100 Hz ; Time Period = 1/100 =10msec
Phase = 0◦
20 Sin(2 ℿ(30) t + 90)
Amplitude = 20. ; Frequency = 30 Hz ; Time Period = 1/30 =
33.33msec; Phase = 90◦
5 Sin(500 ℿ t + 180)
