![]() Make sure the MSB out is connected to the MSB in. Connect the input of the D/A converter to the output of the A/D converter. Using Multisim, use the A/D converter to digitize a sine-wave input signal and then reconvert the representative digital signal into an analog signal with the DAC (in Multisim this is called a VDAC). Test the accuracy of the digital voltmeter with several different values for analog in. Calibrate the digital voltmeter by applying 5V to the analog in (measured with a DVM) and adjusting the potentiometer until the 7 segment display reads 5.0 (the decimal point is assumed to be in the middle). Note that the 2 least significant A/D output bits are left unconnected (using only 6 bits of resolution). The 74185 will be used to convert a 6-bit binary number to a 2-digit BCD number. Using Multisim, construct a simple 0-5V DC digital voltmeter using the ADC (rather than the ADC0804) and the 74185 to convert the binary output into BCD, which will be displayed on two 7-segment displays.
