CS302 Current Spring 2011 Final Term VU Paper [July 2011] Virtual University of Pakistan

Question No: 01

 The divide-by-60 counter in digital clock is implemented by using two cascading counters:

       ► Mod-6, Mod-10                  ► Mod-50, Mod-10

       ► Mod-10, Mod-50                ► Mod-50, Mod-6 

2)      A Nibble consists of _____ bits

        ► 2       ► 4          ► 8       ► 16

3) The voltage gain of the Inverting Amplifier is given by the relation ________

       ► V_out / V_in = - R_f / R_i          ► V_out / R_f = - V_in / R_i

       ► R_f / V_in = - R_i / V_out         ► R_f / V_in =   R_i / V_out
