Digital signals transmitted on a single conductor (and a ground) must be transmitted in:

• Slow Speed
• Parallel
• Medium Speed
• Serial

Which waveform is used to represent an Voice Signal?

• Sinusoidal Waveform
• Square Waveform
• Staircase Waveform
• Trianglular Waveform

Which waveform is used to represent an Digital Signal?

• Sinusoidal Waveform
• Clock Pulse
• Staircase Waveform
• Trianglular Waveform

The parallel transmission of digital data:

• is much slower than the serial transmission of data
• requires only one signal line between sender and receiver
• requires as many signal lines between sender and receiver as there are data bits
• is less expensive than the serial method of data transmission

Serial format means digital signals are:

• sent over one conductor sequentially
• sent over many conductors simultaneously
• sent in groups of eight signals
• sent in binary coded decimal
