Frequency Modulation

Frequency modulation is a method or process of encoding the data of a specific signal (analog or digital) by modulating the carrier wave frequency according to the frequency of the modulated signal. Modulated signals are nothing more than information or data that should be conveyed after being converted into electronic signals.

Question

Q1/ A) Find the sampling frequency for the following signals:
1) S1 = 20 cos(1500t) * cos (4000nt)
500nt.
2) S2 =
[sin
nt
[sin4000nt
3) S3 =
* 5 cos(1200nt)
nt
B) The following waveform is the RB (return to bios) representation of the serial
digital data, find the digital data code and draw the NRZ (non-return to zero) and
RZ (return to zero) waveforms.
C) The waveform below is the PAM for the analog signal, draw the analog signal,
PWM and the PPM for this signal.
