Sensor Specifications:

Analog-to-Digital Conversion Specifications:

Sytem Noise:

- There is signifigant noise at 20kHz during transmission between the amplifier and the A/D converter -->

The filter's cut-off frequency needs to be set at 1kHz above the highest frequency component of signal of interest.The passband gain needs to be 1.

Determine:

(1) Amplifier that should take upt he entire dynamic range of the A/D converter. Assume all operational amplifiers are ideal. Ensure loading doesn't happen. Hand-Drawn Schematic

(2) Design a filter to meet specifications set. Use the smalest oder filter possible. Minimize parts and include the transfer function H(omega) and a MATLAB plot.

(3) Determine the number of bits on the A/D converter and lowest possible sampling frequency.

(4) Assume the sampled input to the A/D converter is 3.58 volts. Determine the binary output.

so far -->

Explanation / Answer

so the valur of R1 should be selected according to the calue of Rf depending upon the configuration in which it is connected.
