6 8 The following figure shows a certain type of counter. All the JK flip-flops are positive edge triggered. (The JK flip-flops toggle the output value after each positive clock edge when both J and K are connected to 1.) The preset and clear pins are all connected to "1". JO and KO are connected to "1" 2. The initial value of Q2 Q1 00 are O. K1 (a) Sketch the output waveforms for lo, e and e the figure. (b)Describe the function of the counter. rite down the output value (such as "000", "001") for each clock period on svnchronous/ asynchronous? Binary up/down counter? Counting from ? to 2)
