A Resistance Capacitance (RC) Coupled Amplifier is basically a multi-stage amplifier circuit extensively used in electronic circuits. Here the individual stages of the amplifier are connected together using a resistor–capacitor combination due to which it bears its name as RC Coupled.

Advantages of RC coupled amplifier:

  • It makes use of resistors and capacitors which are not not expensive so the cost of RC coupled amplifier is low.
  • The circuit is very compact and extremely light.
  • The frequency response of RC coupled amplifier is excellent.
  • It offers a constant gain over a wide frequency range.

Disadvantages of RC coupled amplifier:

  • It has low voltage and power gain.
  • It is unsuitable for low frequency application.
  • t has the tendency to become noisy with times.
  • It has narrow bandwidth.

Hence for the given question, statements 1,2 and 3 are corrrect.

The question given below consists of a statement, followed by three arguments I, II and III. You have to decide which of the arguments is/are ‘strong’ arguments is/are ‘weak’ arguments and accordingly choose your answer from the alternatives given below each question. Statement: India's burgeoning shadow finance sector is likely to face a shake-up after defaults at one major lender battered the nation's financial markets in the past week and reinforced worries about credit risk. Industry officials and experts say they expect Indian regulators to cancel the licences of as many as 1,500 smaller non-banking finance companies because they don't have adequate capital, and to also make it more difficult for new applicants to get approval. Which of the following argument(s) stated support(s) the given fact? Arguments: I. Better capitalised and more conservatively run finance firms are likely to swallow up an increasing number of smaller rivals. That could make it difficult for many small borrowers to get loans, especially in the countryside where two-thirds of India's 1.3 billion people live and put the brakes on a surge in private consumption with a knock-on effect on growth.  II. The shadow banking sector now comprises more than 11,400 firms with a combined balance-sheet worth 22.1 trillion rupees ($304 billion) and is less strictly regulated than banks. It has been attracting new investors, particularly as the nation's banks have had to slow their lending as they seek to work through $150 billion of stressed assets.  III. Nearly 11,000 of India's NBFCs are small and medium-sized businesses with an asset base of less than 5 billion rupees. But the top 400, many of which are backed by banks and finance companies, control about 90 percent of the assets under management.

Deviation is the algebraic difference between a size and the corresponding basic size. Which of the above statements is/are correct ? 
Consider the following statements regarding modulation : 1. The communication systems, where a weak signal is transmitted by the use of a modulation is essential in carrier signal. 2. When the frequency of the high frequency signal is varied in accordance with the intensity of the low-frequency weak signal, the modulation is said to be frequency modulation. 3. The process of recovering original baseband signal from the modulated signal is called phase modulation. Which of the above statements are correct ?
