Hello all
I need some help with the following questions.
Please don't just give the answer but rather show me the formula/method to solve the problems.
1. A tachometer displays engine RPMs from zero to 10,000. If the ADC accepts voltage levels from zero to five volts, in order to achieve full-scale representations from the tachometer, what should the output voltage be at 8500RPM?
2. An ADC converter has a binary input of 0010 and an analog output of 20mv. What is the resolution?
3. A given 4-bit digital to analog converter has a reference voltage of 15 volts and a binary inout of 0101. What is the proportionality factor?
4. The _______ of a DAC is the smallest change that can occur in the analog output as a result of a change in the digital input. (Fill in the blank)
I have more unanswered question but I'll leave it at that for now.
Many thanks.
