In the common mode, Select one:
a. both inputs are grounded
b. an identical signal appears on both inputs
c. the outputs are connected together
d. the output signals are in-phase
In the common mode, the correct answer is (b) an identical signal appears on both inputs.
In electronics, the common mode refers to a condition where both inputs of an amplifier receive the same signal with the same polarity. This can occur due to external noise or interference, or due to a fault in the circuitry.
When the same signal appears on both inputs, it creates a common-mode voltage, which is a voltage difference between the input terminals that is common to both signals. This common-mode voltage can cause distortion in the output signal of the amplifier.
To avoid this, amplifiers are designed with a common-mode rejection ratio (CMRR), which is a measure of the amplifier's ability to reject common-mode signals. A high CMRR means that the amplifier can reject common-mode signals effectively, and produce a clean output signal.

True. In theory, we could create a decision tree that perfectly fits the training data by creating a separate path for each example, and always returning the correct output label for that example.
However, such a tree would be overfit to the training data and would not generalize well to new, unseen examples. Instead, we aim to create a decision tree that generalizes well to new data by finding the simplest tree that fits the training data reasonably well. This is achieved by selecting the attribute to split on that gives the highest information gain, as well as by pruning the tree to remove branches that do not improve its generalization performance.

When querying a HDB, to what column should the where clause point to first?
The WHERE clause in a query on a HDB should point to the column that has an index on it first, if possible. This is because an index allows for faster searching and retrieval of data based on the values in that column.
When an index is used, the HDB does not need to scan the entire table to find the matching rows, but instead, it can quickly jump to the relevant parts of the index and retrieve the data. If the WHERE clause does not point to an indexed column, the HDB may have to scan the entire table to find the relevant data, which can be slower and less efficient.
However, it is also important to consider other factors when selecting the column for the WHERE clause, such as the selectivity of the column (how many distinct values it has) and the cardinality of the index (how many rows share the same value). In some cases, it may be more efficient to use a non-indexed column for the WHERE clause if it has high selectivity or a low cardinality index.

Reactor ballast have many negative characteristics such as:
a. they are not NEC approved
b. starting current is greater than the operating current
c. high cost
d. only multi-tap voltages available
Reactor ballasts are not commonly used in modern lighting systems because they have several negative characteristics that make them less desirable than other options. One of the main reasons is that they are not NEC approved, meaning that they do not meet the safety standards set by the National Electrical Code.
This can make them risky to use in certain applications, particularly those that involve high voltage or complex wiring. Another issue with reactor ballasts is that their starting current is often much greater than their operating current. This can put a strain on the electrical system, leading to potential problems such as flickering lights, tripped breakers, and damaged equipment. In addition, reactor ballasts tend to be more expensive than other types of ballasts, which can make them less appealing from a cost standpoint.
Finally, reactor ballasts typically only come in multi-tap voltage options, which can limit their flexibility in certain lighting applications. While they may be suitable for certain industrial or commercial settings, they may not be the best choice for more specialized or nuanced lighting needs. In conclusion, while reactor ballasts may have been a popular option in the past, their negative characteristics have made them less desirable in modern lighting systems.
