A constant input analogue voltage of 5.2V is input to a 4-bit successive approximation ADC. The ADC has an input range of 0-16V, the maximum binary output possible being 1111 – for any input voltage greater than 15V. List and explain the sequence of interim approximations that will be output by the register/DAC and the converter’s final output.
Group Members Class Assignment 3 A DAC uses a reference voltage of 100 V and has 8-bit precision. In four successive sampling periods, each a second long, the binary data contained in the output register were 10000010, 01111100, 01110101, and 01101000. Suppose that a second order hold were to be used to generate the output signal. The equation for the second-order hold is the following: E(t) -E+ at + B, where Eo starting voltage at the beginning of the time...
