ECE 3050 Analog Electronics Quiz 14 November 25, 2009 Professor Leach Name Instructions. Print your name in the space above. Place a box around your answers. 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. Draw the diagrams of circuits which can be used to realize the voltage-gain transfer functions given. It may be helpful to f rstdrawthestra ight - l ineBodemagn itudep lots .Inthesecond through fourth transfer functions, assume that ω 1 2 .
