Description:
I am looking for an experienced professional with expertise in high-speed Nyquist-rate ADCs to provide guidance and teaching on key concepts. We are seeking an experienced professional specializing in high-speed Nyquist-rate ADCs to provide in-depth teaching and guidance on fundamental and advanced concepts in this domain. The ideal candidate should have expertise in ADC design, digital signal processing (DSP), and related signal manipulation topics.
Most importantly, to provide detailed guidance on the AFE7950IABJ part
Requirements:
Strong expertise in high-speed ADCs, including Nyquist-rate ADCs, digital signal processing (DSP), and FFT concepts.
Ability to clearly explain concepts such as Nyquist zones, oversampling, noise spectral density (NSD), and the behavior of signals during decimation and filtering.
Candidates will need to answer the following questions during the selection process:
Q1: Why is only the 1st Nyquist zone preferred for signal sampling?
Q2: What happens if the second-order harmonics (or higher orders like the 3rd and 4th) fall into the sampled input frequency range after DDC (Digital Down Conversion) is performed?
Q3: What is FFT, and how is it created from a time-domain signal in the context of an HB1 (Half-Band Filter 1) in a high-speed Nyquist-rate ADC?
Q4: When the HB1 (Half-Band Filter 1 in a high-speed Nyquist-rate ADC) is enabled and the complex-to-real conversion block is enabled, with a decimation rate equal to one, what is the behavior or effect?
Q5: How can we visualize the FFT as
sampling frequency / number of samples
sampling frequency/number of samples, and what does "number of samples" mean in this context?
Q6: How does oversampling improve SNR?
Q7: How does oversampling reduce noise power and increase SNR?
Q8: How does noise spread equally across the spectrum?
Q9: How should we interpret the Noise Spectral Density (NSD)?
Q10: How is NSD represented in terms of dBFS/Hz?
Q11: For a Nyquist-rate ADC, how is the noise spread across the entire Nyquist band (fs/2)
? Why does noise only spread within the Nyquist zone?
Q12: After sampling, how will the signal in the 3rd or 4th Nyquist zones appear in the time domain?
Deliverables:
One-on-one teaching sessions (virtual).
Share a full syllabus covering all essential and advanced topics in high-speed ADCs.
Practical insights or examples to deepen understanding.
Guide practical simulations for better understanding of ADC operations and signal processing.
If you are an expert in this domain and AFE7950IABJ and can provide structured and clear guidance, please apply with your qualifications and answers to the sample questions listed above.
hello sir, I am an Electronics engineer with specialization in Telecommunication. I will be available to do the online virtual classes. However, answering these questions is most probably proper at a discussion call. Let me know if you feel interested. I have experience at doing Digital signal processing projects for many years.
Let me know if you feel interested.
This proposal outlines my plan to take over the project involving high-speed Nyquist-rate ADC guidance. My goal is to provide end-to-end support, covering technical education, practical insights, and simulation assistance, to ensure the project's success and meet its objectives.
