Phase-sensitive Demodulation
(problem 8.) Given the sinusoid plot x(t)c(t) from t=0 to t=0.3. time scale is 0.02.
3
Phase-sensitive Demodulation
Given x(t)c(t)=y(t), find x(t) LPF y(t) O(t)=? Filtered by Low Pass
4
Phase-sensitive Demodulation
Given the sinusoid plot x(t)c(t).
5
Capacitive Sensor (problem 9.) (a)Find Cx(t) using x(t) and maximum,minimum Cx(t). chest
6
Capacitive Sensor (b) Find Vo(t).
7
Capacitive Sensor (c) Phase-sensitive demodulation LPF Vo(t) Vi(t)

Capacitive Sensor (problem 10.) A B C D
9
Capacitive Sensor Find Vi using x0,a,(P1-P2) and Vs. constant constant
10
Capacitive Sensor (b) Find Gain of IA with 0.1[V/mmHg] sensitivity, when Vs=1[v],Xo=100[um],a=2[um/mmHg]. (c) Phase-sensitive demodulation In order to make 0.1 sensitivity, Gain should be 10. + LPF Vo(t)
