Topic 1 - Intro to Signal and System

The statement below are true about signal, except

• It is a function that conveys information about a phenomenon

• It can be defined as function of one or more variable

• The information carried by a signal will be a function of an independent variable

• It consist only of one channel of source

Below are the example of one channel signal, except

• Image

• Audio

• ECG Signal

• EEG Signal

The given picture is classified as

• Continuous time, continuous value signal

• Continuous time, discrete value signal

• Discrete time, continuous value signal

• Discrete time, discrete value signal

The given picture is classified as

• Continuous time, continuous value signal

• Continuous time, discrete value signal

• Discrete time, continuous value signal

• Discrete time, discrete value signal

Discrete time and discrete value signal is often called as digital signal

• True

• False

The natural form of signal is analog signal

• True

• False

The statement below are true about system

• System is interconnection of physical devices and component

• A system is anything that responds when stimulated or excited

• System can use feedback to improve system performance

• All the above
