Question

1. A system can transmit and receive data. However, it can only transmit or receive at one time. This is an example of a. Full - duplex b. Half-duplex 2. You have a switch attached to a digital pin configured as an interrupt. When the switch changes state (high to low or low to high) you want to run an ISR. What interrupt pin action would be best to use in this application? a. LOW b. CHANGE C. RISING d. FALLING 3. The communication between the serial monitor in Arduino IDE and the microcontroller board is an example of what type of communication? a. Synchronous b. Asynchronous A peak detector is using the following values, R 2200 2 peak detector output in figure 1 (yellow trace) looks the way it does. What can be adjusted to make the output look more like figure 2 4. and C 1uF. Explain why the

Explanation / Answer

1. Half duplex. Because in half duplex send and receive of data can be done but not at a same time but in full duplex simultaneous send and receive of data can be done.

2. Change. Because if raising or falling is used then either low to high or high to low are detected but not both. Of change is used both low to high or high to low can be used.

3. Asynchronous. In asynchronous both ends have to agreed on the speed of communication called baud rate.whereas in synchronous clock signal is used to match both ends speed.

4. When time constant RC is high then discharging time is more and charging time is more. If RC is low then charging time is less and discharging time is less. So if we increase the value of resistor or capacitance then discharge will not occur more so waveform will be look in fig 2
