Draw the basic circuit of an R-C phase-shift oscillator and explain its operation. If $ R_1=R_2=R_3=450 \text{ k}\Omega $ and $ C_1=C_2=C_3=60 \text{ pF} $, determine the frequency of oscillation in phase-shift oscillator.

A new clocked X-Y flip-flop is defined with inputs X and Y in addition to the clock input. The flip-flop functions are as follows:
If $ XY=00 $ the flip-flop changes state with each clock pulse.
If $ XY=01 $ the flip-flop state Q becomes 1 with the next clock pulse.
If $ XY=10 $, the flip-flop state Q becomes 0 with the next clock pulse.
If $ XY=11 $, no change of state occurs with the clock pulse.
Write the truth table and excitation table of X-Y flip-flop. Implement the X-Y flip-flop using a J-K flip-flop.
