Digital Signal Processing

Any physical phenomenon that carries some information is

• System

• Processor

• Signal

• None

The two basic types of signals are analog and:

• Digilog

• Digital

• Vetilog

• Sinewave

The interface between an analog signal and a digital processor is

• D/A converter

• A/D converter

• Modulator

• Demodulator

Which of the following characterizes an analog quantity?

• Discrete levels represent changes in a quantity.

• Its values follow a logarithmic response curve.

• It can be described with a finite number of steps.

• It has a continuous set of values over a given range.

The process of conversion of continuous time signal into a discrete time signal is known as

• Aliasing

• Sampling

• Convolution

• None of the above

Which type of signal is represented by discrete values?

• Nois signal

• Non linear

• Analog

• Digital

Scientific notation is a method

• of expressing a very large number

• of expressing a very small number

• used to make calculations with large and small numbers

• All of the above

Any unwanted signal interfering with the main signal is

• System

• Noise

• Frequency

• None

Signal processing undergoes a change in

• Amplitude

• Phase

• Freuency

• All of the above

Quantized and coded version of the discrete time signals are

• Analog signals

• Digital signals

• Both A and B

• Coded signal
