a) [6 pts] The frequency of the source current in the circuit is adjusted until vo is in phase with ig. What is
the value of o in radians per second? (Hint: if vo is in phase with ig, the phase of total impedance must be
zero (Ztot = vol ig), which means the phase of total admittance is zero. It will be easy to work with
admittance in this question because the components are in parallel.)
b) [2 pts] What is the total impedance at the frequency found in (a)?
c) [2 pts] Ifig=2.5 cosoot mA (where o is the frequency found in [a]), what is the steady-state expression
for vo?

- Write code to generate a PFM signal output to an output pin and then view it via an oscilloscope. The amplitude of the input signal should be changeable by pressing a button and the button presses should be counted via LEDs connected to the microcontroller. Specification: 1. When you start the program, nothing happens and all LED off. 2. When button pressed, use a starting frequency of 1kHz (and LED count 1) 3. With every new button pressed, frequency multiplies by 2 (i.e 2kHz, 4Khz, et.c) and the LED counts accordingly (i.e 2, 3, 4, …,7 and then go back to 0). 4. When the count is 7, it restarts from 0 again (meaning all LEDs are OFF and no signal at the oscilloscope) Recommended Steps: 1. Connect the Switch and the 3 LEDs 2. Connect the limiting resistors to the LED and the pull-up resistor to the switch (The resistor values will be determined in the lab) 3. Write the code to count the button presses (remember to debounce it if necessary) 4. Now generate the Pulses for each count.…arrow_forwardThe device should boot up into the off state, that is, no LEDs are lit. On the depression of a switch on the development board, the first LED color should light and be steady. You you can use any LED colour combinations as you wish. On the depression of a switch a second time, the second LED color should flash with an on time of x msecs where the on duration is specified in the attached PDF and total cycle time of 1 second. The LED should remain flashing until the switch is depressed and the system returns to the off state and return to the start of the state transitions. This should form a cycle: off, steady, and then flashing. In addition, we are going to be storing variables in the EEPROM. You are to write into the EEPROM information so that when the board powers up again, the color of the lights are reversed. Steady should be the second color and flashing should be the first color given to you.
