Perform the assembly of Figure 1 (typically pren-dre R = 1 k and C = 100 nF) and study the frequency behavior of the harmonic filter.
Measure its cutoff frequency fc at - 3 dB and compa-rer to the theoretical value.
What mathematical operation makes this filter when f << fc? (for some form of an input signal).
Study in each case below the filter response to a triangular signal or created-neau, frequency: f << fcoupure (f take on the order of fc / 20);
f ≈ fcoupure;
f fcoupure >> (f take on the order of 20 * fc).
