Question

measurements. please show work to all. Thanks!

Remark Do not use computer software. Use a calculator only, and show your calculation process Q1. We have an analog signal Y[V] sin(2π*St). We are collecting this signal with a sampling frequency 20 Hz with analog-to-digital (A/D) converter. Draw the output of A/D converter. (0.4pt) Voltage Voltage YIV] sin(2n*5t) 0.5 0.0 0.5 Time (s) 0.0 0.0 0.2 0.4 0.10 0.20 0.30 0.40 Time (s) Q2. Calculate the resolutions for the 2-bit, 8-bit, 12-bit, and 16-bit analog-digital converter: Input and output signal ranges from -15V to 15V. (0.4pt) 1) 2-bit: 2) 8-bit: 3) 12-bit: 4) 16-bit: Q3. We are using a 3-bit analog-digital converter (i.e., Arduino) to collect a sensor signal ranging from 0 to 15V. The sensor linearity error is +1bit and sensor offset drift is +1 bit in a full range Estimate the measurement uncertainty (voltage) by the analog-digital converter. (0.4pt) Q4. We have 6 different signals with a frequency of lHz, 100Hz, 300Hz, 500Hz, lkHz, and 2kHz NI myDaq is used as a data acquisition unit. The sampling frequency is 1.5kHz. (0.8pt) Which signals out of 6 signals can we collect with NI my Daq (sampling frequency 1.5kHz) based on the Nvquist Theorem Remark: Do not use computer software. No calculation process, No point.
