Practical exercises with LTSpice

Exercises description

Take measurements in the frequency and linear time domain:
- differentiating circuit,
- integrating circuit,
- uncompensated oscilloscope probe,
- compensated oscilloscope probe
- overcompensated oscilloscope probe.

Determine the frequency at which the transmittance in the passband decreases by 3 dB.

Below is a diagram of the differentiating circuit (Fig. 1) and the integrating circuit (Fig. 2). Use resistors: \( R=3 k\Omega \), \( C=51nF \).



For oscilloscope probe, use \(R_1=27k\Omega\), \(R_2=3k\Omega\), \(C_2=51nF\) and determine C1 from the compensation condition. The figure below shows the uncompensated oscilloscope probe (fig. b) and the compensated oscilloscope probe (fig. c). Derive the compensation condition.


When you're done, compare the result with the video:
