Increase the input signal frequency and note the effect on the resultant output signal. Set the analog input signal frequency to 200Hz and observe the resultant analog output signal. NI Multisim Live lets you create, share, collaborate, and discover circuits and electronics online with SPICE simulation included. Use an oscilloscope to compare the analog input and output waveforms. Adjust the Vref/2 voltage using the potentiometer so that the analog input span on the ADC is 0 to 2.5V. Adjust the input sine wave to 2.5Vp-p with a DC offset of 1.25 volts (i.e., the sine wave goes from 0 to 2.5V). Make sure the MSB out is connected to the MSB in. Interfacing 7 Segment Display with Arduino - Circuit WebCircuit design 7 segment display common anode created by maria liakopoulou with Tinkercad Webden. 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.
