Question

Which of the following statements are not correct?

(A) Precision rectifiers use positive feedback to compensate for the forward drop of the diodes

(B) Precision peak detector uses a capacitor to effectively lengthen the duration of the peaks

(C) Limiters may be thought of as programmable signal clippers

(D) In order to improve performance of comparators negative feedback may be used

(E) There are two basic approaches for realizing a design : (1) using zener diodes and (2) using biased-signal diode network

Choose the most appropriate answer from the options given below:

(1) (A) and (D) only

(2) (D) and (E) only

(3) (A) and (C) only

(4) (B) and (D) only

1. 1
2. 2
3. 3
4. 4

Answer 1

Correct Answer - Option 1 : 1

Let us analyze every statement.

Statement (A):- Precision rectifiers do not use positive feedback, hence statement A is wrong.

Statement (B):- Peak detector uses a capacitor to store the peak value of the input signal & its length end the duration of the peak.

Statement (C):- Limiters are also called signal clippers.

Statement (D):- In comparators either positive or no feedback is used. Hence Statement (D) is wrong.

Statement (E):- Zener diodes & biased-signal diodes are used to design various electronic applications.
