1. 

(a)   i.  Explain the importance of noise immunity for a digital  circuit       

       ii.  Explain the operation of the bipolar transistor as a logical switch

(b)   i. Implement a two-input AND gate using CMOS.                                                                                                                 

       ii. Implement a two-input OR gate using CMOS.

(c)   Define multivibrator and Explain various types of multivibrator with their          

applications.

(d)   The output of a multivibrator is given in Figure 2(b). What is the name of this multivibrator? Explain its operation with proper circuit and diagram.

(e)   Determine the value of a capacitor to be used in an astable multivibrator to                                                                                                        

provide a square wave of 1µs side at a repetition rate of 10KHz, where R1 and R2 values 20kΩ.
