Q1. What is CDC and explain the CDC techniques
Ans. 
CDC stands for Clock Domain Crossing. It refers to transferring data between different clock domains in an FPGA design.
• CDC occurs when signals cross between different clock domains in an FPGA design

• CDC can lead to metastability issues if not handled properly

• Common CDC techniques include synchronizers, handshake protocols, and FIFO buffers

• Examples of CDC techniques include 2-flop synchronizers, Gray coding, and CDC FIFO

Q2. Determine the unkonw clock frequency with know one
Ans. 
Use a frequency counter or oscilloscope to measure the period of a known signal and calculate the frequency.
• Measure the period of a known signal using a frequency counter or oscilloscope.

• Calculate the frequency using the formula: Frequency = 1 / Period.

• For example, if the period of the signal is 10 ms, the frequency would be 1 / 0.01 = 100 Hz.

Q1. Where is the fiber broken and how will you fix it?
Ans. 
To determine the location of a broken fiber, I would use an OTDR and then fix it by splicing or replacing the damaged section.
• Use an Optical Time Domain Reflectometer (OTDR) to analyze the fiber and locate the break.

• Once the break is identified, the damaged section can be spliced back together or replaced.

• Splicing involves fusing the two ends of the fiber together using a fusion splicer.

• If the break is severe or in an ...read more

Q1. Design a counter
Ans. 
Design a counter using flip-flops to count up or down based on the input signal.
• Use D flip-flops to store the count value

• Connect the output of one flip-flop to the input of the next flip-flop to create a ripple effect

• Use additional logic gates to control the direction of counting (up or down)

• Implement a reset signal to initialize the counter to a specific value

Q1. Optical fiber working principle
Ans. 
Optical fiber works on the principle of total internal reflection of light.
• Light is transmitted through a core made of glass or plastic

• The core is surrounded by a cladding layer with a lower refractive index

• When light enters the core at an angle greater than the critical angle, it reflects off the cladding and stays within the core

• This allows for high-speed data transmission over long distances

• Examples include fiber op...read more

Ans. 
Optical fiber works on the principle of total internal reflection of light.
• Light is transmitted through a core made of glass or plastic

• The core is surrounded by a cladding layer with a lower refractive index

• When light enters the core at an angle greater than the critical angle, it reflects back into the core

• This allows the light to travel long distances without significant loss of signal
