Consider the following statements regarding Next-Generation Photonic A...
Recently, Next-Generation Photonic Analog-to-Digital Converters (NG-PADC) developed by IIT Madras with support from the IMPRINT programme which is equipped with a time-stretched photonic ADC.
- Analog-to-digital converters (ADCs) are critical components for developing the next generation of advanced digital receivers.
- The limitation of electronic ADCs (EADCs) is that their vertical resolution is compromised at high bandwidths.
- There are two possible approaches to solve this problem through Photonics.
- Radio frequency, when modulated on a spectrally rich optical pulsed source, can be stretched in the optical domain through a dispersive medium, thus converting high-frequency RF signals into effectively low-frequency signals.
- This reduces the input bandwidth requirements of the back-end ADC as many times as the stretch factor of the optical pulse.
- The other Photonic approach is to use an optical clock whose fluctuations in timing (timing jitter) is much smaller an electronic clock; which is possible with a short pulsed laser.
- High bandwidth RF signals, when sampled with stable optical clocks, can provide a much higher effective number of bits (ENOB) compared to electronic clocks.
- It has time-stretched photonic ADC with effective bandwidth 12 times higher than EADC, which enables digitisation of signals with a much larger precision.
- A newly designed prototypes in the Next-Generation Photonic Analog-to-Digital Converters (NG-PADC) project which can carry out instantaneous frequency measurement, generation and transport of Radio Frequency (RF) through optical methods.
- Its effective bandwidth is 12 times higher than a corresponding EADC
- This could revolutionize various sectors, enabling faster digital communication, improved satellite communication, better medical imaging, and Photonic radars.
Hence both statements are correct.

Consider the following statements regarding Next-Generation Photonic A...
The correct answer is option 'C' - Both 1 and 2.
Explanation:
Next-Generation Photonic Analog-to-Digital Converters (NG-PADC) are a new generation of devices that have the capability to carry out instantaneous generation and transport of Radio Frequency (RF) signals through optical methods. They are expected to revolutionize the field of communication and signal processing by providing high-speed and high-resolution analog-to-digital conversion.
1. NG-PADC can carry out instantaneous generation and transport of RF through optical methods:
NG-PADCs use photonic techniques to convert analog RF signals into digital signals. This is achieved by using optical components such as lasers, modulators, and optical fibers to encode the RF signals onto optical carriers. This optical encoding allows for high-speed and high-resolution conversion of the RF signals. Unlike traditional electronic converters, NG-PADCs can perform this conversion with minimal distortion and without the need for bulky and expensive electronic components.
2. NG-PADCs will help in improved satellite communication:
NG-PADCs have the potential to greatly improve satellite communication systems. By using photonic techniques, NG-PADCs can overcome the limitations of traditional electronic converters, such as limited bandwidth and high power consumption. This means that satellite communication systems using NG-PADCs can transmit and receive signals at higher frequencies and with higher data rates, leading to improved communication performance.
NG-PADCs can also enhance the efficiency and reliability of satellite communication systems. The use of optical components allows for the integration of multiple functions into a single device, reducing the size and complexity of the system. This can lead to cost savings and increased system robustness.
In conclusion, both statements are correct. NG-PADCs have the capability to carry out instantaneous generation and transport of RF through optical methods, and they have the potential to improve satellite communication systems.
