24.What 24 .What are the limitations of the basic Integrat Integrator or circuit?

At   low frequency, a integrator may become unstable and break into oscillations, The input At im pedance decreases decreases with decrees in frequenc frequency y. 25. What is a comparator?

Which compares a signal with a known reference voltage . its output is either + Vsat or -Vsat .

29.What is a multivibrator?

It is a regenerative circuit that is used extensively in timing applications. It has two states

either stable or quasi-stable depending on the type of multivibrator. 30.What is monostable multivibrator?

Generates a single pulse of specified duration in response to each external trigger signal. It has only one stable state. Its is also called as One-shot generator. 31.What is an astable multivibrator?

It is a free running oscillator having two quasi-stable states. So it is a Square wave generator. 32.What is a bistable multivibrator?

Bistable multivibrator is one that maintains a given output voltage level unless an external trigger is applied .Application of an external trigger signal causes a change of state, and this http://eceschool.blogspot.i n/ n/2016/10/Li ne near -I -Integr at ated- ci ci rc rcui ts ts- la lab- Vi Vi va va- Qu Questions- Pa Par t2 t2.html
