COMM2

is the transmittal of digital signals between two

or more points in a communications system

• Digital signal processing

• signal processing

• digital transmission

• digital processing

The primary advantage of digital transmission over analog transmission is

• Better compatibility in multiplexing

• Noise Immunity

• regeneration

• Signal Processing

Digital signals are also better suited than analog signals for processing and combining using a technique called

• Multiplexing

• Signal Processing

• regeneration

• digital transmission

digital transmission systems are more resistant to analog systems to additive noise because they use signal ___________ rather than signal amplification.

• regeneration

• enhancing

• multiplexing

• cancelling

is the processing of analog signals using digital methods and includes bandlimiting the signal with filters, amplitude equalization, and phase shifting.

• Digital signal processing

• digital transmission

• noise immunity

• band limiters

consists essentially of sampling analog information signals and then converting those samples into discrete pulses and transporting the pulses from a source to a destination over a physical transmission medium.

• Pulse modulation

• pulse width modulation

• pulse position modulation

• pulse length modulation

is sometimes called pulse duration modulation

(PDM)

• pulse position modulation

• pulse width modulation

• pulse code modulation

• pulse amplitude modulation

•The pulse width is proportional to the amplitude of the analog signal

• PWM

• PAM

• PCM

• PPM

•the position of a constant-width pulse within a prescribed time slot is varied according to the amplitude of the sample of the analog signal.
