Q:

Analog synthesis refers to a technology based on

A) placing brief digital recordings of live sounds under the control of a synthesizer keyboard. B) interfacing synthesizer equipment.
C) representing data in terms of measurable physical quantities. D) representing physical quantities as numbers.
 
Answer & Explanation Answer: C) representing data in terms of measurable physical quantities.

Explanation:

Analog synthesis uses a mixture of complex sounds that are shaped by filtering. It is based on representing data in terms of measurable physical quantities, in this case sound waves.

Q:

An electron and a proton starting from rest get accelerated through potential difference of 100kV. The final speeds of the electron and the proton are Ve and Vp respectively. Which of the following relations is correct?

A) Ve > Vp B) Ve < Vp
C) Ve = Vp D) Cannot be determined
 
Answer & Explanation Answer: A) Ve > Vp

Explanation:

Both when accelerated through a potential difference of 100KV, they will have the same energy. The mass of the electron is less than the mass of a proton, hence it will move faster(momentum).

Q:

In a bipolar junction transistor

A) all the three regions (the emitter, the base and the collector) have equal concentrations of impurity B) the emitter has the least concentration of impurity
C) the collector has the least concentration of impurity D) the base has the least concentration of impurity
 
Answer & Explanation Answer: D) the base has the least concentration of impurity

Explanation:

In terms of concentration of impurity (a.k.a impurity doping concentration, often abbreviated to doping concentration), from the highest to the lowest among the three regions of a bipolar junction, emitter, collector, and base are the correct order. The above order is independent of the type of BJT, npn or pnp
