An analogue sensor signal is sampled every 0.4ms to convert it into a digital representation. what is the corresponding sampling rate?
according to the sampling theorem (section 3.3.1), for this sampling rate value, what will be the highest frequency in the digital representation, assuming the lowest frequency in the sensor signal is very close to zero.
if each sample is quantised into 2048 levels, what will be the resulting bit-rate, giving your answer in scientific notation to 2 decimal places?
hint: firstly, you need to calculate the number of bits per sample that produces 2048 quantisation levels (see section 3.3.2).
