The question seems to involve solving various parts of an exercise related to biomedical instrumentation with focus on operational amplifiers (Op-Amps), filters, and circuit analysis. Here's a breakdown of how I can assist you with some specific questions:

To start solving the problem:

1. For part 1.d, the problem relates to noise affecting the voltage $V_{u1}$, which is influenced by parasitic components. You're tasked to compute the minimum number $N$ of circuits to achieve a desired attenuation of noise components. The noise components are outside the range of interest, and you're supposed to use a filter with a transfer function determined by an ideal Op Amp configuration (represented in the circuit).

2. Step 1.e, requires you to write the overall transfer function of the filter $G_{\text{filter}}(s)$ and to draw the Bode magnitude plot, both asymptotic and actual. This plot helps understand the frequency behavior of the system.

3. Step 1.f is focused on computing the cutoff frequencies, verifying if the temperature signal falls within the frequency range of the filter.

4. Step 1.g involves deriving the value of $V_{u2}$ and drawing the pattern of $V_{u2}$ as a function of temperature, considering the influence of noise and the low-pass filter.

I will now focus on Step 1.d based on the information you provided. The filter configuration is determined by placing $N$ circuits in series, so that the noise is attenuated.

Would you like me to start by explaining the transfer function or focusing on specific calculations for part 1.d (filter components, noise attenuation, etc.)? Feel free to let me know how you'd like to proceed!
