7.

The order of an active filter depends on the number of transistor circuits it contains.

True    False

8.

Monotonic means that the stopband has no ripples.

True    False

9.

If a rippled passband is acceptable, the Chebyshev and elliptic filters are the filters of choice.

True    False

10.

An LC filter has an order of two because it contains two reactive components, an inductor and a capacitor.

True    False

11.

Monolithic op amps are inexpensive, versatile, and reliable.

True    False

12.

Linear circuits include comparators, waveshapers, and active diode circuits.

True    False

13.

A comparator has two input voltages and one output voltage which is either a low or a high voltage.

True    False

14.

A Lissajous pattern appears on an oscilloscope when harmonically related signals are applied to the horizontal and vertical inputs.

True    False

15.

Some optimized comparators have diode clamps built into input stages in order to protect sensitive circuits.

True    False

16.

The trip point of a comparator is located in the center of the linear region.

True    False

17.

If the output swing of a zero-crossing detector is too large for an application, back-to-back zener diodes can be used and the output will be bounded.

True    False

18.

A comparator is sometimes called a limit detector because a positive output indicates that the input voltage exceeds a specific limit.

True    False

19.

Thermal noise is caused by speaker wires located in an environment with a high ambient temperature.

True    False

20.

A comparator that uses positive feedback is called a Schmitt trigger.
