28. The waveform pattern in Figure 8-61 is required. Devise a ring counter, and indicate how it can be preset to produce this waveform on its Q9 output. At CLK16 the pattern begins to repeat. 11 12 13 14 15 16 17 18 19 110 i 11 12 i 13 i 14i 15 Qy 01 00 o

find the average power consume by RL  for both fullwave and halfwave rectifier circuit.

HIGH J QO Q1 CLK CLK CLK K K FF0 FF1 CLK QO Qla Qlb Qlc Qld Figure 9-1 The counter shown in Figure 9-1 is a(n) counter, and the correct output waveform for Q1 is A asynchronous, Q1c B synchronous, Q1b synchronous, Q1d D synchronous, Q1a asynchronous, Q1b
