28a . Given : Annalee is testing an electronics circuit in the lab. There is some pesky high frequency noise at around 3600 Hz with an amplitude around ± 0.3 volts. She uses a 12-bit A/D converter to sample data from the circuit. The data acquisition system is set up with a range of -5 to 5 V, and she builds a low-pass filter to filter out the high frequency noise. To do : Calculate the gain ( G ) necessary to attenuate the 3600 Hz noise to a level that is below the quantizing error of the A/D converter. Give your answer to three significant digits. Solution : 28b . Given : [ Same setup as previous problem ] Annalee is testing an electronics circuit in the lab. There is some pesky high frequency noise at around 3600 Hz with an amplitude around ± 0.3 volts. She uses a 12-bit A/D converter to sample data from the circuit. The data acquisition system is set up with a range of -5 to 5 V, and she builds a low-pass filter to filter out the high frequency noise.
