This article uses Arduino with PWM to teach the step response in RC circuits, since Arduino enables real-time data acquisition and visualisation, connecting theory to practice.The research seeks to illustrate the step response of an RC circuit using Arduino, deepen knowledge of first-order systems...
If there are many resistors in the circuit: R eq is the equivalent resistance of resistors. The key to working with a source-free RC circuit is finding: 1.The initial voltage v(0 + ) across the capacitor. 2. The time constant . Source-free response: The response is due to the i...

Here’s a simple example comparing voltage step responses between a series RC circuit and a parallel RL circuit: Click to open and simulate the circuit above. Can you predict the shape of V(RC) and V(RL) before you run the simulation? Here’s a more advanced example showing how an op-...
Found on some better analog oscilloscopes, this varies the time (holdoff) during which the sweep circuit ignores triggers. It provides a stable display of some repetitive events in which some triggers would create confusing displays. It is usually set to minimum, because a longer time decreases...
Initially, the output sags al- most 200mV due to slow loop response time (the R1-C1 pair delay VC pin (Trace B) response). When the LT1074 comes on response is reasonably quick and surprisingly well behaved considering circuit dynamics. The multi-time constant recovery7 ("rattling" is ...
OPTI-LOOP® com- pensation allows the transient response to be optimized over a wide range of output capacitance and ESR values. The LTC3895 features a precision 0.8V reference and power good output indicator. The output voltage can be programmed between 0.8V to 60V using external resistors ...
A small resistor value (few ohms) in series with the VBIAS can help to limit the pin negative voltage (see Figure 34) during heavy short-circuit events if it is connected to the regulated output voltage. Figure 34. VBIAS in heavy short-circuit event short-circuit current inducVtoBrIAcuSr...
7.2 Control-Loop Gain and Phase-Measurement Procedure The TPS548A20EVM-737 contains a 10-Ω series resistor in the feedback loop for loop response analysis. 1. Set up the EVM as described in Section 5 and Figure 5-2. 2. Connect the isolation transformer to the test points marked TP5 ...
With an input voltage of 20 V and for the part values shown, the circuit provides approximately 10 ms of delay time before the circuit begins switching. Increasing the RC time constant can provide longer delay times. But excessively large RC time constants can cause problems with input voltages...
