Thankyou! this really helps my understandings... but I have one question, what simulation of application did you use for the electrical circuit diagram? how can I use simulations to test an input and see the output signal/graph ? pls help me
nice video! Can you please explain to me the purpose of dividing the voltage? i understand the concept of the voltage divider but not its purpose for this circuit. also, how would one determine the gain for this circuit? last question, the parallel combination of Rf and Cf, does that act as a high pass filter for this circuit? cheers
The conceptual circuit (2:53) requires a dual power supply to allow the op amp output voltage to swing both positive and negative about zero. Note how the the grounded op amp noninverting input is midway between the positive and negative supplies, assuming that they have the same magnitude. With a single-supply op amp the negative power supply is at ground, therefore you need to shift the DC level of the op amp noninverting input to a value midway between ground and the positive power supply; the equal-valued two-resistor voltage divider is an inexpensive way to move the noninverting input to this midpoint voltage. --- The gain of the circuit is the negative reciprocal of capacitance (see 3:55) where the gain is in volts per coulomb. --- The parallel RC elements in the feedback path act as a low pass filter.
The video is interesting. But when I tried to download the book "NI myRIO Project Essentials Guide", it shows "Page Error". Could you help me in getting it?
very helpful and nicely explained! thank you! I am going to attempt making it this week!
