279_Quiz_9_Timers

The ladder logic below represents ZelioSoft code controlling digital outputs Q1 and Q2. T1 is a 2 second on delay (TON) timer. This is known in ZelioSoft as a Function A timer. Complete the timing diagram for the digital outputs Q1 and Q2. There is space allowed on the timing diagram for T1 if you need it. The vertical divisions on the timing chart represent 1 second.

Q5

please type so that i can read your solution

1. A synchronous finite state machine contains a single 'Serial Data' input (SD) and two outputs (S and 7). Output S should be active for one clock pulse every time the input sequence 11010 is detected and output T should be active every time the input sequence 11001 is detected. The functionality of this machine may be partially represented by a timing diagram as shown in Figure 1. Clock a) SD S T Figure 1: Synchronous finite state machine timing diagram Derive the Moore model state diagram for this machine. Hint: ensure that the machine operates correctly even if the bit pattern is preceded by sub-sections of the pattern. [5]

dont use ai and please explainQ1 a) If a 16MHz crystal drives the standard 8051, what is the period of one clock pulse?       b) Calculate the period (duration) to execute the instruction "MUL AB."

use Timer to generate the delay time
