8) TO give you an idea of when to use the LR and RC filters, consider the design of a first
order highpass filter for two different application: an audio application and an RF
application. In both cases the allowable range of the R, C, L values is as follows:
502 <R < 100k
Resistance:
Capacitance: 10pF < C < 10 uF
Inductance
1 uH L< ImH
For each specification below
I
Sketch the magnitude Bode plot of the filter transfer function
II.
Determine the required time constant t of the filter
Sketch both the RC and LR implementations
Determine if it is possible to realize the filter within the R, C, L value constraints
If it is possible, specify the component values that will minimize the C or L value
while meeting the requirement
Ш.
IV
V.
a) For an audio application, design a first order highpass filter with a corner frequency of 1
Hz
b) For a smartphone RF signal path application, design a first order highpass filter with a
corner frequency of 1GHZ (1.0E+9 Hz)
