An analogue sensor has a bandwidth which extends from very low frequencies up to a maximum of 14.5 kHz. Using the Sampling Theorem (Section 3.3.1), what is the minimum sampling rate (number of samples per second) required to convert the sensor signal into a digital representation? If each sample is now quantised into 2048 levels, what will be the resulting transmitted bitrate in kbps? Give your answer in scientific notation to 1 decimal place. Hint: you firstly need to determine the number of bits per sample that produces 2048 quantisation levels

An analogue sensor has a bandwidth which extends from very low frequencies up to a maximum of 14.5 kHz. Using the Sampling Theorem (Section 3.3.1), what is the minimum sampling rate (number of samples per second) required to convert the sensor signal into a digital representation?

If each sample is now quantised into 2048 levels, what will be the resulting transmitted bitrate in kbps?

Give your answer in scientific notation to 1 decimal place.

Hint: you firstly need to determine the number of bits per sample that produces 2048 quantisation levels (see Sections 2.4 (Block 1) and 3.3.2 (Block 3)).
