Explanation: Symmetrical square wave can be obtained by adding a clocked JK flip-flop to the output of Astable multivibrator. The clocked flip-flop acts as a binary divider to the times output and produces 50% duty cycle without any restriction on the choice of resistors. 7. Determine the output frequency of the circuit.
A. 1450Hz
B. 1333Hz
C. 1871Hz
D. 1700Hz
