Understanding Sampling and Quantization
Test your knowledge on the fundamental concepts of sampling, quantization, and frequency analysis in this engaging quiz designed for audio enthusiasts and students alike.
Prepare to answer questions covering:
- Nyquist rate and aliasing
- Fourier theorem and quantization noise
- Filtering techniques and quantization classes
Frequency = ?
T/1
1/T
1/2T
The Nyquist rate is defined as
A frequency of twice the sample rate
Sample rate twice the max frequency
An amplitude of double the bandwidth
A step size of the max frequency
If I have a Fmax of 100, giving a nyquist rate of 200 samplles a second, recalling that nFm +/- nFs for m = 1, 2 etc are my frequency components, what frequency will cause aliasing at the 40Hz level
What is the correct order
High pass filtering, low pass filtering, sampling, quantization
Low pass filtering, high pass filtering, sampling, companding
High pass filtering, sampling quantization, encoding
Low pass filtering, encoding, quantization, sampling
Low pass filtering, sampling, quantization, encoding
To get the amplitude of a triangle wave
Which ones (multiple)are true ya fuck (assumptions abt quantization noise)
The noise is loud
The step size changes with amplitude
The quantizer error is different from the quantizer noise
The quantizer error is uniformally distributed over the steps
The step size is NRZ
The step size is directly related to SNR
When the step size in the quantizer is 𝤃V, the error will be in the interval :
- 𝤃v/2 and 𝤃V/2
𝤃v/1 to T/1
𝤃V/1 and 𝤃V/f
𝤃V/T to 𝤃V/Fmax
