• True

• False

Digitization is the method used in converting analog data to analog signal

• True

• False

• True

• False

Signals are electric or electromagnetic impulses used to encode and transmit data.

• True

• False

Analog data and signals are represented as continuous waveforms that can be at an finite number of points between some given minimum and maximum.

• True

• False

Noise is unwanted electrical or electromagnetic energy the degrades the quality of the signals and data.

• True

• False

The amplitude of the signal the height of the wave above or below the given reference point.

• True

• False

The frequency of the signal is being computed using the formula : F = T/1

• True

• False
