Based on the circuit, program and the given conditions,
(a) Complete the circuit. For the microcontroller, show only the port and pins connected to the DAC. The connections of the DAC0808 and the Op-Amp must be shown in details.
(b) Sketch and label the output waveform of this circuit for 2 cycles. Show the necessary calculations.
(c) Rewrite the given program in C language. Show only the main function. Use the library function Delay10TCY(x) to generate the desired delay.
