The output signal from an analogue sensor is sampled every 195 µs to convert it into a digital representation. What is the corresponding sampling rate expressed in kHz? According to the Sampling Theorem, for this sampling rate value, what approximately could be the highest frequency present in the signal, in kHz, assuming the lowest frequency is very close to zero?

If each sample is now quantised into 512 levels, what will be the resulting bitrate in kbps?

Give your answer in scientific notation to 2 decimal places.

Hint: you need to determine the number of bits per sample that produces 512 quantisation levels.
