1. Data: 101010000111 analog waveform
Solution [1]
The balance of analog flag is vital strategy for remote communication because it
utilizes the channel in productive way and the message flag in computerized bits
are changed into analog remote able signals. The balance method can be
classified agreeing to the parameters being shifted in analog tweaked flag to be
specific amplitude, frequency, or stage. Usually said to be sufficiency move
keying, Recurrence move keying, and stage move keying. Other half breed
procedures like QAM are moreover utilized for tweak. The tweak procedure is
explained below and each one is charted for the information given within the
problem. Data: 101010000111
a) Two level ASK
The amplitude of the carrier signal is the parameter in this case where binary 0 bit
has lower amplitude and higher amplitude at binary 1

b) Frequency shift Keying
The frequency of the carrier is lower in binary 0 bit and at binary 1 bit frequency is
higher. This classification makes it easy to distinguish at receiver and find the actual
message bits.

c) Two level phase shift
In this modulation the phase is altered according to the binary signal. We have
taken 180 degree phase shift as the number of bits to be taken is one at a time. [1]

d) Differential phase shift keying
This a type of phase shift keying which will depend on the binary bits to in
consequence , if binary 1 comes then there is 180 degree phase shift and binary 0
has no phase shift of previous signal.
