decrease the cutoff frequency and discuss the behavior. Tie your discussion back to filter roll-off.
What happens when the cutoff frequency is less than the signal frequency? Why?
6.35 Program Monostable Circuit provides a simulation of a monostable integrated circuit based on the
type 555 op-amp. The trigger controls the simulation. The user can vary the ‘‘on’’ time and values for
R and C. Discuss the output vs. time results for a simulation. Vary R and C to create a 1-s square wave.
6.36 Program 741 Op amp simulates op-amp gain characteristics. Determine if it is noninverting or
inverting and explain. For an input voltage of 1 V, find a resistor combination for a gain of 5. What is
this op-amp’s maximum output? Repeat for a gain of 0.5.
