The ratio of the RMS value of additional frequency components in output to the RMS value of the original output of the amplifier is called __________

Correct Answer: Intermodulation distortion
The ratio of the RMS value of additional frequency components in output to the RMS value of the original output of the amplifier is known as intermodulation distortion. These additional frequency components can be harmonics, as well as sums and differences of the original frequencies, as well as the sum and differences of the harmonics.

A small and medium enterprise imports two components A and B from Taiwan and China respectively and assembles them with other components to form a toy. Components A contributes to 10% of production cost while components B contributes to 20% of production cost. Usually the company sells this toy at 20% above the production cost. Due to increase in the raw material and labour cost in both the countries ,component A became 20% costlier and components B became 40% costlier. Owing to these reasons the company increased its selling price by 15%. Considering that cost of other components does not change. What will be the profit percentage if the toy is sold at the new price?

The ratio of the RMS amplitude of the higher order harmonic frequencies to the RMS amplitude of the fundamental frequency is commonly called __________

In designing with op amps one has to check the limitations on the voltage and frequency ranges of operation of the closed-loop amplifier, imposed by the op-amp finite bandwidth (ft), slew rate (SR), and output saturation (Vo max). Consider the use of an op amp with ftt = 2 MHz, SR = 1 V/µs, and V0 max = 10 V in the design of a non-inverting amplifier with a nominal gain of 10. Assume a sine-wave input with peak amplitude Vi. If Vi = 0.5 V, what is the maximum frequency before the output distorts?

A cosine wave voltage signal has a 10V RMS value and 60Hz frequency. Also at time, t=0, the value of the voltage signal is equal to its RMS value. Which of the following is the correct mathematical representation of the voltage signal?

cascading two identical amplifier stages, each having a low-pass STC frequency response with a 3dB frequency f1, results in an overall amplifier with a 3dB frequency given by

A step-down delta-star transformer, with per-phase turns ratio of 5 is fed from a 3-phase 1100 V source. The secondary of this transformer is connected through a 3-pulse type rectifier, which is feeding an R load. The power delivered to the load is 6839.3 Watts.
