### 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 ...

### How to set the sampling frequency for this filter+

I need to make a passive LP anti-aliasing filter(recommended cut off freq.). Filtered signal from an hotwire-anemometer will be measured by DAQ has 100Meg input impedance. The thing is that my ...

### A very basic question about response time of an instrument

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 of between choosing low or high response time?...

### Find impulse response for given difference equation

I have trouble understanding this. I am given this difference equation: $$y[n+2]-3y[n+1]+2[n] = 2u[n+1] -2u[n]$$ and I need to find the response for Kronecker delta function. I can do z transform ...

### 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 ...

### 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 ...

### RLC Response (Overdamped, Underdamped, and Critically damped)

Ive got a question about identifying the overdamped, underdamped, and critically damped waveforms of an RLC circuit. From my (very basic understanding), underdamped decays while oscillating. ...

### 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:...

### How to find the step and impulse response of a circuit with a diode

I have a circuit similar to the following: simulate this circuit – Schematic created using CircuitLab I am trying to find the impulse and step response mathematically. I know I can split the ...
