Answer:
What is a capacitor?
Capacitor, a electronic component to hold charges, represented by the letter C. It composes of two metal electrodes between a layer of insulating dielectric. When a voltage is applied between the two metal electrodes, the charge is stored on the electrode, so the capacitor is an energy storage electrical part. Any of two conductors that are insulated and close to each other form a capacitor. In addition, the parallel plate capacitor consists of the electrode plate and the dielectric of the capacitor.
Capacitor is one of the widely used electronic components in electronic equipment. It is widely used in stopping DC and alternating AC, coupling, bypass, filtering, tuning loop, energy conversion, control and so on. Capacitor is different from capacitance. The capacitance is the basic physical quantity, the symbol C, the unit is F (Farah).

Explanation:
Creating an even parity circuit in Multisim involves designing a digital logic circuit that checks if the number of '1's in a binary input is even. If the input has an even number of '1's, the circuit should output '1' (indicating even parity); otherwise, it should output '0' (indicating odd parity).
Here's how to create an even parity circuit in Multisim, along with the truth table:
**Creating the Even Parity Circuit:**
1. Open Multisim and create a new blank schematic.
2. Add the following components to your schematic:
- Input pins (for binary input bits)
- XOR gates
- An AND gate
- An inverter (NOT gate)
- Output display (LED or probe)
3. Connect the input pins to the XOR gates. Each input pin corresponds to one bit of the binary input.
4. Connect the outputs of the XOR gates to the inputs of the AND gate.
5. Connect the output of the AND gate to the input of the inverter (NOT gate).
6. Connect the output of the inverter to the output display.
7. Label your input pins for clarity (e.g., A0, A1, A2, ...).
**Designing the Even Parity Truth Table:**
To create the truth table for even parity, you'll need to list all possible input combinations (binary numbers) along with the corresponding output (even or odd).
Assuming you have a 3-bit input (A2, A1, A0), here's the truth table:
| A2 | A1 | A0 | Output (Even Parity) |
|----|----|----|-----------------------|
| 0 | 0 | 0 | 1 (Even) |
| 0 | 0 | 1 | 0 (Odd) |
| 0 | 1 | 0 | 0 (Odd) |
| 0 | 1 | 1 | 1 (Even) |
| 1 | 0 | 0 | 0 (Odd) |
| 1 | 0 | 1 | 1 (Even) |
| 1 | 1 | 0 | 1 (Even) |
| 1 | 1 | 1 | 0 (Odd) |
Each row in the truth table represents a unique combination of input bits (A2, A1, A0) and specifies whether the output is '1' (Even) or '0' (Odd).
Once you have created the circuit in Multisim and designed the truth table, you can simulate the circuit to verify its functionality. Ensure that the circuit produces the expected output (even parity) based on the input values.
b. a pitch lower than the original pitch.
c. an amplitude lower than the original amplitude.
d. a frequency higher than the original frequenc
Correct answer choice is:
D. A frequency higher than the original frequency.
Explanation:
This is a true case of Doppler's effect. The Doppler effect can be defined as the effect originated by a traveling source of waves in which there is a visible higher variation in pulse for observers towards what the source is progressing and a visible descending shift in rate for observers from what the source is dropping.
