Better than that of each stage

Worse than that of each stage

Same as that of each stage

None of the above

The element has negative temperature coefficient

The current / voltage curve has negative slope

The element has negative specific resistance

The current / voltage curve has a positive slope

Of the problem of drift with differentiating circuits

Because of the poor efficiency

Because of the complex circuitry requirements

The noises are amplified and this can be significant in the output.
