When amplifying a triangular wave using an operational amplifier, the most significant characteristic to consider is the slew rate of the op-amp. The slew rate defines the maximum rate at which the output voltage can change per unit time, typically expressed in volts per microsecond (V/µs). For a triangular waveform, which has a constant slope, the output of the op-amp must be able to follow this slope accurately without distortion. If the op-amp’s
