Network

• Device

• Diode

• Circuit

• Equipment

Symmetrical network

• Electrical properties are affected

• Electrical properties are not affected

Asymmetrical network

• Input and output terminal can be changed

• Input and output cannot be changed

Equaliser

• Removes distortion

• Adds distortion

• Needs distortion

If equaliser removes phase distortion is called

• Attenuator

• Filter

• Phase equaliser

If equaliser removes amplitude distortion

• Low pass filter

• Symmetrical network

• Amplitude equaliser

Attenuator

• Reduce input signal

• Increase input signal

• Adds input signal

Following is one type of filter

• Symmetrical

• Equaliser

• High pass filter

Low pass filter

• Allow high frequency

• Allow low frequency

• Allow band of frequency

Filter allow high frequency is called

• Band pass filter

• High pass filter

• Low pass filter
