Which digital signal processing technique takes preventive measures to protect the transport streams from errors caused by noise and interference in the transmission channel in DTV transmitter and receiver?

Which digital signal processing technique takes preventive measures to protect the transport streams from errors caused by noise and interference in the transmission channel in DTV transmitter and receiver? Correct Answer FEC (Forward Error Correction)

The FEC encoder takes preventive measures to protect the transport streams from errors caused by noise and interference the transmission channel. Forward error correction (FEC) is a Digital Signal Processing technique used to enhance data reliability. It does this by introducing redundant data called error correcting code, prior to data transmission or storage. FEC includes Reed-Solomon coding, Outer interleaving, and convolutional coding.

Read the following passage and answer the item that follows. Your answers to this item should be based on the passage only. We live in digital times. The digital is not just something we use strategically and specifically to do a few tasks. Our very perception of who we are, how we connect to the world around us, and the ways in which we define our domains of life, labour and language are hugely structured by the digital technologies. The digital is everywhere and, like air, invisible. We live within digital systems, we live with intimate gadgets, we interact through digital media, and the very presence and imagination of the digital has dramatically restructured our lives. The digital, far from being a tool, is a condition and context that defines the shapes and boundaries of our understanding of the self, the society, and the structure of governance. Which among the following is the most logical and essential message conveyed by the above passage?
In a receiver the input signal is 100 V, while the internal noise at the input is 10 V. With amplification the output signal is 2 V, while the output noise is 0.4 V. The noise figure of receiver is

The question given below consists of a statement, followed by three arguments numbered I, II and III. You have to decide which of the arguments is/are ‘strong’ arguments and which is/are ‘weak’ arguments and accordingly choose your answer from the alternatives given below each question. Statement: In an interview with ETCIO.COM, Kuruvilla Markose, Chief Digital Officer of Titan shares his perspective on how technology is serving the company’s digital vision and the various initiatives that he is spearheading to hone the competitive edge of Titan. He is the first CDO to be appointed by the software conglomerate Tata Group. He is the man who has put the Titan’s digital transformation on fast-track. Which of the following arguments support the fact that Kuruvilla Markose has put Titan’s digital transformation on fast-track? Arguments: I. Markose is a man with a vision. He is the first CDO to be appointed by the software conglomerate Tata Group. He has spent his entire two decade long career in Tata Group. He has been in customer facing roles across different group companies.  II. His CDO role is horizontal and supports Titan’s myriad business lines: watches, jewellery, bags, perfumes wallets, and eye-wear. But the man and his words are grounded. Diny, as he is popularly known, is a man of measured speech and bearing. III. “Digital innovation”, according to Markose, is all about creating value for the customer. To him, customer centricity is the road to longevity in the digital age. Under his stewardship, Titan has launched a panoply of digital initiatives aimed at improving customer centricity.
