Exciting an RC Circuit at its TRUE Pole on the Sigma (Real) Axis in the Left-Half Plane

Yeah, you probably are reading this question and thinking I'm one of those engineers who hasn't learned about the s-plane. I can assure you I'm not! I know that the transfer function of an RC circuit (Vout/Vin) has a REAL pole, with no imaginary…

Flash ADC's nonlinear output and response

I don't understand this paragraph about flash ADC. A flash converter can produce a non-linear output which is an additional advantage. The voltage divider network consists of equal-value resistors which provide a proportional response. But for…

Why a system is causal if the impulse response is zero for \$t<0\$?

I was reading a definition that Suppose \$h(t)\$ is the impulse response of any system \$Y\$, then the system is causal if and only if \$h(t)=0\$ for \$\forall t<0\$ I know what a causal system is, but I don't understand it in terms of the…

Settling time in 2nd order response (circuit)

I understand the definition of settling time defined as "time took to reach within +-2% (or 5) of the converged value". Then does it mean settling time cannot be defined when the response converges to zero?

What is meant by the response time of a temperature transducer?

Regarding a temperature transducer, what is meant by response time in this context? It says it can be set to < 30 ms or < 300 ms. Is there any trade off between choosing low or high response time?

Find the transfer function given responses

We have an open loop system with an input u , a transfer function G(s) and an output y. We apply the following inputs $$u_i(t)=\sin(ω_it), i=1,2,...6 $$ and get the following responses These are of the form $$y(t)=Y_1\sin(ω_it+ψ_i)$$ Seeing some of…

Impulse response of a LTI TD system

Why the impulse response of this system: \$y(n)=\sum_{|k|\leq3}^{}x(n-k)\$ is: \$h(n)=\sum_{|k|\leq3}^{}\delta(n-k)\$ and the impulse response of this one: \$y(n)=\sum_{k=0}^{+\infty}x(n-k)\$ is: \$h(n)=u(n)\$ ?

what is the surplus-control of generation?

Reading the ''P1 – Policy 1: Load-Frequency Control and Performance'' document, published by UCTE in 2009 (it is available on internet for all) I noted that there are many contributions to Load-Frequency control from the electric power system. In…

How does negative feedback control system begin to work fast

Let us consider an open loop system, which has some value of bandwidth. Now, when the loop is closed via negative feedback, the gain of the system reduces and the bandwidth of the system increases. Increased bandwidth implies quick response time.…

The zero-input and zero-state response of a circuit consisting only of a dc source and a capacitor?

From my understanding, the zero-input and zero-state responses of an RC circuit can be found by solving for the homogenous and particular solution of the ordinary differential equation found using Kirchhoff's current law. But I am confused as to…

How do I find the second order transfer function from this response graph?

I am trying to find the second order transfer function from this response graph, however since I can't find the correct overshoot value I'm stuck. The graph runs from 0 to 10 seconds and starts at 1 second. The acceleration starts at 0 and ends at…

Help needed using convolution to calculate a system's impulse response

I have a circuit with the transfer function \$G(s) = \frac{1}{(s+1)^2}\$ and I'm asked to calculate the impulse response of the circuit. After looking into it I know that I need to use convolution with the delta function to solve this. I've managed…

Is the charge accumulation linear in time for image sensors?

Reformulating the question: Does the rate of charge of the pixels photodiodes in an image sensor depends of the previous accumulated charge? The pixel sensor integrates light during a specific amount of time called exposure time. Suppose that the…
