It involves converting standard logic levels to a form more suitable for transmission
through digital communications systems.

• PCM Coding

• Encoding

• Folded Binary Coding

• PCM Sampling

A reason for encoding is that Digital Communications isn't widely used.

• True

• False

Which is not a Line Encoding Format?

• UPNRZ

• BPRZ

• BPNRZ

• UPBRZ

What type of Line coding is shown in the figure?

• BPRZ AMI

• UPRZ

• BPRZ

• BPNRZ

It is not really a type of modulation but rather a form of
digitally coding analog signals.

• Pulse Code Modulation

• Pulse Modulation

• Pulse Position Modulation

• Pulse Amplitude Modulation

Still works if synchronization between transmitter and receiver fails

• PAM

• PPM

• PWM

• PCM

the position of a constant-width and constant-amplitude pulse is varied according to the amplitude of the
sample of the analog signal.

• PPM

• PWM

• PAM

• PCM

the amplitude of a constant-width, constant
position pulse is varied according to the amplitude of the analog signal.

• PCM

• PPM

• PWM

• PAM

is the most prevalent form of pulse modulation, wherein the analog signal is sampled and then the sample
is converted to a serial n-bit binary code.

• PPM

• PAM

• PCM

• PWM

Which is not true with regards to the types of Pulse Modulation?

• PWM: Widest pulse could represent the highest amplitude of analog signal.

• PPM: The rightmost pulse could represent the maximum amplitude of the analog signal.

• PAM: The minimum amplitude of the pulse could represent the maximum
  amplitude of the analog signal.

• PCM: Resulting signal has fixed length and fixed amplitude.
