WebbExpert Answer 100% (5 ratings) Transcribed image text: PRESET CLEAR The preset and clear inputs to a J-K flip-flop are HIGH (1). Which of the following is true? The Q output is immediately set to 1. The flip-flop is free to respond to its J, K, and clock inputs. The Qoutput is in an ambiguous state. The Q output is immediately cleared. lithodora cuttings lithodora pruningWebbIf the input to the flip-flop has a Schmitt trigger design, you can use a simple R-C divider across the rails. Connect the reset line to the center of the divider. If you need a high value for reset and a low for operation, connect the resistor to ground and the cap to +Vcc.
