MB MC Overview 1 a Chapter l introduces the concept of scarcity as applied in economics(also the No-Free-Lunch Principle). It presents the unavoidable fact that our needs and wants are unlimited and resources available to satisfy them are limited
The lowpass filter H(u) has a cutoff frequency wc=205T rad/ sec. Thus, c(t)is r(t) where all terms with frequency above we are removed by the lowpass filter. The terms which are kept have kwol 205T rad /sec k|< 10.25, so the output, ac(t),is r(t)= To obtain n, we sample c(t) every T=5 10-3 seconds with an impulse train The sampling frequency is 400T=2 x maximum frequency in c(t). Therefore
