Question 4
Statement(I): Many of the linear control system transfer functions of not have poles or zeros in the right half of s-plane.
Statement(II): These are called minimum phase transfer functions.
Statement(II): These are called minimum phase transfer functions.
Question 5
A 4-bit D/A converter gives an output voltage of 4.5 V for an input code of 1001. The output voltage for an input code of 0110 is.
Question 6
What is the combined energy density of electric and magnetic fields, if magnetic field in a space has a value 1*10-2T with electric field as 2.0*106 V/m.
Question 7
Which one of the following statements is not correct?
Question 8
In ship to ship communication, the problem of fading can be overcome by using
Question 9
A potentiometer is a device that is used for measuring:
Question 10
Assertion (A): When a transistor is taken from hard saturation state to OFF, the storage time plays a significant role in deciding the turn OFF time of the transistor.
Reason (R) : The excess minority carrier concentration in the base region should die down by recombination process which mostly contributes to the storage time during the turn OFF process of the transistor.
