Expression (A6) is valid if l/ws ^ 1/coi + RzCz . The denominator of the 

 expression indicates a falUng 6 db per octave asymptote with a corner, 

 frequency at ws . The second factor in the denominator can be approxi-

then the circuit has a rising 12 db per octave asymptote with a corner 

 frequency at C03 . Fig. 7(b) shows the amplitude and phase of the current 

 transmission.
