What are the basic continuous time signals? Draw any four waveforms and write their equations

 Basic continuous time signals:

    These are the standard test signals which are used to study the properties of systems. Basic CT signals posses some specific characteristics that are used for systems analysis. 

The Standard signals are, 

i. Unit Step signal 

ii. Unit Impulse signal 

iii. Unit ramp Signal 

iv. Complex Exponential Signal
