Mell What is meant by time base generator?
A time base generator (also timebase or time base) is a special type of function generator, an electronic circuit that generates a varying voltage to produce a particular waveform.
What are the features of time base signal?
Features of a Time Base Signal A cathode ray tube and also a picture tube works on the same principle. The beam deflects over the screen from one side to the other (generally from left to right) and gets back to the same point. This phenomenon is termed as Trace and Retrace.
What is time base circuit definition?
: a part of an electronic circuit having a voltage varying accurately with time and used (as in radar) to provide range information or (as in television) to time the scanning operation.
What are the types of time base generator?
TYPES OF TIME BASE GENERATORS 1) UJT as RELAXATION OSCILLATOR. 2) MILLER SWEEP GENERATOR. 3) BOOTSTRAP RAMP GENERATOR. 4) CURRENT TIME BASE GENERATOR.
What is time base voltage?
Definition: The generator which is used for generating the linear variable voltage concerning time is known as the time base generator. These waves are used in cathode ray tube for deflecting the beam in a horizontal direction. The velocity operates with the deflecting voltage increases linearly with the time.
What is the definition of a time base generator?
What is a Time Base Generator? An Electronic generator that generates the high frequency saw tooth waves can be termed as a Time Base Generator. It can also be understood as an electronic circuit which generates an output voltage or current waveform, a portion of which varies linearly with time.
Is the saw tooth generator a time base generator?
An Electronic generator that generates the high frequency saw tooth waves can be termed as a Time Base Generator. It can also be understood as an electronic circuit which generates an output voltage or current waveform, a portion of which varies linearly with time.
How are time base generators used in oscilloscope?
To display the variations of a signal with respect to time on an oscilloscope, a voltage that varies linearly with time, has to be applied to the deflection plates. This makes the signal to sweep the beam horizontally across the screen. Hence the voltage is called as Sweep Voltage. The Time Base Generators are called as Sweep Circuits.
Why are sweep circuits called time base generators?
These circuits are also known as sweep circuits. This is so because they are used to sweep the beam of electron across the screen in a horizontal direction in CRO. Voltage time-base generator: It generates a voltage that varies linearly according to time and finds its application in electrostatic deflection.
