2. You need to build a square-wave oscillator with duty cycle of 50%. The output should oscillate between 0 and 10 volts. The frequency should be 1500 Hz. Also for consistency sake use Rcap-35K2. For this please draw a schematic. Specify the capacitor value and the resistors as well as the supply voltage values
write down the pseudocode to generate a 200μs period square wave with a 25% duty cycle. You do not need to write any Assembly, just explain the method you would use to generate this type of square wave. 3,

3 Design Problems Design problems should be worked by the lab team, and each lab team submits one design solution. In this section, you will: Design an RC circuit for a pulse-width modulated (PWM) variable voltage source Analyze your circuit to determine the transient response . Pulse-width modulators are often used to control a DC voltage by adjusting the duty cycle of a square wave. Applications of PWM include controlling motor speeds for radio-controlled drones and electric drills To simulate...
