#### Question 6
**What is the return result of the dB2 function from the following code?**
```python
import math
def dB2(param1, param2):
dB_calc = 20 * math.log10(param1/param2)
if dB_calc > 6:
return "High SNR"
elif dB_calc > 0:
return "Low SNR"
else:
return "Noise"
print(dB2(5,5))
```
**Options:**
- O Noise
- O High SNR
- O Low SNR
- O 0
**Explanation:**
The given Python function `dB2` calculates the signal-to-noise ratio (SNR) in decibels. Here is a step-by-step breakdown of the function:
1. **Importing the math module**: The `math` module is imported to facilitate mathematical operations.
2. **Defining the function `dB2` with two parameters `param1` and `param2`**:
- It calculates the dB value using the formula: `dB_calc = 20 * math.log10(param1/param2)`.
3. **Conditional checks**:
- If `dB_calc` is greater than 6, it returns `"High SNR"`.
- If `dB_calc` is greater than 0 but less than or equal to 6, it returns `"Low SNR"`.
- If `dB_calc` is less than or equal to 0, it returns `"Noise"`.
4. **Function Call**: The function is called with parameters 5 and 5 (`print(dB2(5,5))`).
**Calculation**:
- Since param1 is equal to param2, `dB_calc` becomes 20 * log10(5/5) = 20 * log10(1) = 20 * 0 = 0.
Thus, the function will return `"Noise"`.
**Correct Answer**: Noise

#### Question 5
Suppose you have a list defined in the following way:
```
myList = [[12, 11, 10], [9, 8, 7], [6, 5, 4], [3, 2, 1]]
```
What are the correct dimensions of this list?
- [ ] 12 x 1
- [ ] 3 x 4
- [x] 4 x 3
- [ ] 1 x 12
[Save & Continue]
[Report an issue with this question]
#### Explanation
The provided list `myList` is a two-dimensional list (often referred to as a matrix). It consists of 4 rows and 3 columns. Each sub-list within the main list is a row containing 3 elements. Therefore, the correct dimensions of `myList` are 4 rows by 3 columns (4 x 3).](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fa9ed15ea-b247-4d4a-84f5-d7f808a88737%2Fd5bebb00-6098-4094-a1e3-062e9f13bcb3%2Fbfcwexen_processed.jpeg&w=3840&q=75)
