Honor Code Statement: I have neither given nor received help on this quiz. Initials 1 of 2. (a) The block diagram of an oscillator is shown. For s = , what are the conditions on A ( s ) and b ( s ) for steady state oscillations? A ( ) b ( )=1 6 0 . (b) If A ( ω 0 )=5 6 60 , what must be the phasor value of b ( 0 ) for steady-state oscillations at the frequency ω 0 ? b ( 0 )= A 1 ( 0 )=0 . 2 6 60 2 of 2.
