Explanation: As the resistor value increase or decrease, the frequency of triangular wave will decrease or increase, respectively. Therefore, the amplitude of the triangular wave decreases with an increase in it frequency and vice verse. 3. Which among the following op-amp is chosen for generating triangular wave of relatively higher frequency?
A. LM741 op-amp
B. LM301 op-amp
C. LM1458 op-amp
D. LM3530 op-amp
Answer:A
Explanation: As the resistor value increase or decrease, the frequency of triangular wave will decrease or increase, respectively. Therefore, the amplitude of the triangular wave decreases with an increase in it frequency and vice verse. 3. Which among the following op-amp is chosen for generating triangular wave of relatively higher frequency?
A. LM741 op-amp B. LM301 op-amp C. LM1458 op-amp D. LM3530 op-amp
Explanation: The frequency of the triangular wave generator is limited by the slew rate of the op-amp. LM301 op-amp has a high slew rate. 4. What is the peak to peak (PP) output amplitude of the triangular wave?
