transfer chara

We were doing analog circuits lab for which our instructor asked us to construct a circuit from the transfer characteristics (I have attached the image.) We were working on RC integrators, differentiators, clipping and clamping circuits, and I can't figure what circuit would give a transfer characteristics like this. Could you help me out please?

Also, is fourier transform somehow related to this? I remember me plotting amplitude response of fourier transforms of cos and sin functions, and they looked similar to these transfer characteristics.

  • \$\begingroup\$ @MathKeepsMeBusy It is the plot of transfer characteristics of some RC circuit. (input voltage on x-axis, output voltage on y-axis) \$\endgroup\$

    \$\begingroup\$ The figure looks like a two-axis Cartesian plot with two vertical line segments drawn on it. If those line segments represent the locus of your "function", a transfer function it is not. \$\endgroup\$

    \$\begingroup\$ That diagram doesn't make much sense to me. You should talk with your instructor or a TA, so they can figure out what concept you're having trouble with, and clear it up for you. \$\endgroup\$

transfer chara Here is the answer: It is the transfer characteristics of a good integrator, when a square wave is applied to the input (i.e., triangular wave is obtained at output. We tried to find the transfer characteristic of integrator circuit today, and obtained this in CRO.

  • \$\begingroup\$ Nope. A transfer characteristic is independent of the input signal. That’s the whole point of calling it a characteristic, vs. “exemplary output response for a square wave”. That’s what caused everyone trouble. Integrators have no fixed transfer characteristic in fact, since their response depends on time. A transfer characteristic is static in terms of time! For an integrator the transfer characteristic must include time, and a graphical way of conveying it would be with a block diagram made up of transfer functions in the s-domain for example. I think your instructor is confusing students. \$\endgroup\$

  • \$\begingroup\$ In fact, there’s a wild variety of circuits that will have this “transfer characteristic” for any signal, statically, whereas an integrator acts that way only when driven with a square wave. \$\endgroup\$

  • \$\begingroup\$ @Kubahasn'tforgottenMonica Just today we were told that transfer characteristic is dependent on input signal. It is very confusing, especially since our concepts are not strong. \$\endgroup\$
