I applied via Campus Placement and was interviewed in Jul 2022. There were 2 interview rounds.
Digital Electronics, verilog basics,C language basics,
Designing a digital system for detecting start bit in UART communication
The start bit is the first bit in a UART transmission and is always a logic low
The system should sample the incoming data at a rate higher than the baud rate to accurately detect the start bit
A shift register can be used to store the incoming data and detect the start bit
The system should also check for framing errors and parity errors

I was interviewed in Sep 2017.
Overlap-add is implemented by dividing the input signal into overlapping segments, applying a window function, and adding the segments together.
Overlap-add is a method used in digital signal processing to efficiently convolve long signals with finite impulse response (FIR) filters.
The input signal is divided into overlapping segments, typically with a length equal to the filter length.
A window function, such as the Ham...
The Nyquist criterion states that in order to accurately sample a signal, the sampling rate must be at least twice the highest frequency component of the signal.
The Nyquist criterion is used in digital signal processing to prevent aliasing.
It ensures that the sampling rate is sufficient to capture all the information in the signal.
The criterion is based on the concept of the Nyquist frequency, which is half the samplin...
Demodulating a QAM signal involves separating the amplitude and phase components to recover the original data.
QAM signals combine amplitude and phase modulation
Demodulation involves separating the amplitude and phase components
Techniques like coherent demodulation and quadrature demodulation are used
Coherent demodulation uses a local oscillator to recover the phase component
Quadrature demodulation separates the in-phas
Interpolation in discrete-time domain involves estimating values between known data points.
Interpolation is used to fill in missing data or estimate values between known data points.
Common interpolation methods include linear interpolation, polynomial interpolation, and spline interpolation.
Linear interpolation calculates values by drawing a straight line between two adjacent data points.
Polynomial interpolation uses a...
Yes, I would take the intern in Hyderabad to mentor and guide them in their learning journey.
Taking an intern can provide an opportunity to mentor and guide a budding engineer.
It can also help in delegating tasks and projects, allowing for more productivity.
Having an intern can bring fresh perspectives and ideas to the team.
Interns can also assist in research and development projects, aiding in innovation.

To determine maximum frequency of operation from a complex diagram
Identify the critical path in the diagram
Calculate the propagation delay of each component in the path
Use the formula fmax = 1 / (2 * propagation delay) to determine maximum frequency
Consider any setup or hold time requirements for flip-flops or other components
Ensure that the frequency is within the specifications of the components used
The minimum size of buffer depends on burst rate, input/output stream rates, and latency rate.
Calculate the maximum amount of data that can be received during the latency period
Determine the maximum burst rate and the maximum input/output stream rates
Calculate the buffer size using the formula: buffer size = (maximum burst rate * latency period) + maximum input/output stream rates
Consider adding extra buffer space for
