i. Design a circuit using 555 timer, which will flash the electric bulb such that it's ON time will be 7 seconds and OFF time will be 2 second. (5 Marks) ii. Find the phase error necessary to produce a VCO frequency shift of Af = 15 KHz for an open loop gain of Ky= 30 KHz/rad. What will be the deviation of phase error if Af shifts to 6 KHz? (5 Marks) i.
