CP8.9 Design a filter, G s ( ), with the following frequency response: 1. For < 1 rad s, the magnitude 20 log10 G

CP8.9 Design a filter, G s( ), with the following frequency response:

1. For ω < 1 rad s, the magnitude 20 log10 G j ( ) ω 

< 0 dB

2. For 1 1000 < < ω  rad ,s the magnitude 20 log10

G j ( ) ω ≥ 0 dB

3. For

ω > 1000 rad ,s the magnitude 20 log10

G j ( ) ω < 0 dB Try to maximize the peak magnitude as close to

ω 4 = 0 rad s as possible.
