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

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
