Exam 19: Active Filters Key

Which filter offers the advantage of three simultaneous outputs: low-pass,high-pass,and bandpass?

In terms of damping,the Butterworth response is

How is all serious filter design accomplished?

Predistortion refers to decreasing the design value of Q as needed to compensate for a limited gain-bandwidth product.

The bandwidth of a bandpass filter is the sum of its upper and lower 3-dB cutoff frequencies.

A filter that blocks all frequencies from zero up to the cutoff frequency and passes all frequencies above the cutoff frequency is the

When used to compensate for the time delay of another filter,the all-pass filter is sometimes called a

Which filter has a fast roll-off,but has ripples appear in the passband of the frequency response?

A method used to correct for limited GBW is ________.

The graph of a filter's voltage gain versus its frequency is the filter's
