It is desired to design a system that digitally samples a signal whose source and components are unknown; For this process, Timer (8253A), ADC(ADC0804), PPI(8255) are required to be used. The \INTR end of DAC0830, ADC0834, 8255, 8253A Timer and ADC are placed at predetermined addresses. You are expected to find these addresses. The \INT end is connected to the D4 end after passing through the tristate buffer. The steps you need to do are; 1. Make your Timer and 8255data connections. 2. The minimum required to digitally sample a signal Find the sampling frequency. 3. The maximum output of a signal that can be sampled without problems with a sampling rate of 20hz Find the frequency. 4. The sequence required to sample the analog signal at 20 hz for 5 seconds Calculate the size. 5. With an 8254 timer circuit to sample the analog signal at 20hz frequency It is desired to use 8255 and ADC together. Calculate the required settings of these circuits. (You can set the clock value to any value you want) 6. Write the asm code that samples the analog signal for 5 seconds at 20hz frequency using ADC. 7. Demonstrate using a frequency DAC that it samples the signal you sampled in a loop 8. You will need to show the signals with the help of an oscilloscope... Note: You can make any changes you see fit in the design. Tips: You should set the timer circuit to produce a pulse in the range of 20hz, and each time a pulse is produced, you should read from the ADC. You can control the pulse value produced from the ADC with the help of 8255. Nyquist
