Which signal types are represented by a continuous waveform?
Analog
When you do modulation in time domain you get modulated waveform of modulating signal information and carrier. How can you recognize the upper and lower side bands in time domain modulated waveform?
You need modulation signal(carrier) which is a required signal in order to make envelope of time domained signal(target signal). The modulating signal is imposed on modulation signal.This creates envelope of waveform which is modulated(desired) signal. Now, the desired signals uper and lower sideband of signal strictly depends on modulation signal's bandwidth. Max. peak of that signal is uper sideband and min. peak is lower sideband for this modulated signal.
What is the bandwidth of DSBSC?
BW=2 fm
Attenuators are the opposite of a what?
An attenuator is the opposite of an amplifier. An attenuator is used for reducing the power of a signal. An attenuator is able to do this without modifying the waveform of the signal.
What is the wave form of clipping circuit?
As a sinusoidal signal is clipped the waveform approaches a square wave.

Drawing the waveform of analog signal?
Should be a sine ( or cosine) wave.

What is the device called that converts electrical signal to sound waveform?
It is called a speaker.

As a sinusoidal signal is clipped the waveform approaches a square wave.
What is a cycloconverter?
A cycloconverter or a cycloinverter converts an AC waveform, such as the mains supply, to another AC waveform of a lower frequency, synthesizing the output waveform from segments of the AC supply without an intermediate direct-current link.
What does the line on a graph from an oscilloscope represent?
The waveform of the electrical signal in terms of amplitude on y and period in x.
Why do you get a inverted waveform when a AC signal is passed to a amplifier?
Due to its negative gain and 180' phase shift between base and collector
What is a schmitt trigger?
A COMPARATOR CIRCUIT WHICH CONVERTS ANY ARBITRARY SIGNAL(SLOPE!=1) TO SQUARE WAVEFORM IN SHORT A AMPLITUDE COMPARATOR
