5. The following electronic system is designed to process measurements from an accelerometer that produces the input voltage signal v,(t). 0.1 uF 120 ΚΩ 10 ΚΩ 10 k2' 0+ V₁(1) v₂(t) V3(1) · 40 ΚΩ For a practical measurement situation, the signal v, is periodic and can be characterized by the Fourier series: v₂(t) = 1.6 sin (1,000) + 0.8 sin (2,000) + 0.4 sin (3,000+) + .... The amplitude (volts) of the fundamental component in v(t) is most nearly: A. 1.6 B. 1.13 C. 0.56 D. 0.3
