Basic Filters
True or False

Mark each of the statements below True or False.

1 .       In an RC low-pass filter, the output voltage is taken across the resistor and the output lags the input voltage. [Hint]

 
 


2 .       In an RL low-pass filter, the output voltage is taken across the inductor and the output lags the input. [Hint]

 
 


3 .       In an RC high-pass filter, the output is taken across the resistor and the output leads the input. [Hint]

 
 


4 .       In an RL high-pass filter, the output is taken across the inductor and the output leads the input. [Hint]

 
 


5 .       The roll-off rate of a basic RC or RL filter is 20 dB per decade. [Hint]

 
 


6 .       A band-pass filter rejects frequencies between the lower and upper critical frequencies and passes all others. [Hint]

 
 


7 .       A band-stop filter passes frequencies between its lower and upper critical frequencies and rejects all others. [Hint]

 
 


8 .       The bandwidth of a resonant filter is determined by the quality factor (Q) of the circuit and the resonant frequency. [Hint]

 
 


9 .       Critical frequencies are also called -3 dB frequencies. [Hint]

 
 


10 .       The output voltage is 63.3% of its maximum at the critical frequencies. [Hint]
