Let's write the Python program to perform the above steps:```import jsonfile_name = "state_info.csv"dict_data = {}with open(file_name, encoding='utf-8') as file:for line in file:line_data = line.strip().split(",")abbrev, state_name, capital, population = line_datadict_data[abbrev] = [state_name.strip(), capital.strip(), int(population)]with open("state_json.json", "w") as file:json.dump(dict_data, file)with open("state_json.json", "r") as file:json_data = json.load(file)states = [state for state, data in json_data.items() if data[2] > 5000000]print(states)```

In this assignment, we are supposed to write a Python program to read a CSV file consisting of U.S. state information, then create and process the data in JSON format. The following are the specific steps to do so:

1. Read a CSV file of US state information, then create a dictionary with state abbreviation as key and the associated value as a list: {abbrev: [state name, capital, population]}.

2. Create a JSON formatted file using that dictionary. Name the file ‘state_json.json’.

. Visually inspect the file to ensure it's in JSON format.

4. Read the JSON file into your program and create a dictionary.

5. Search the dictionary to display the list of all state names whose population is greater than 5,000,000.The notes to keep in mind while writing the program are:• The input file of U.S. state information will be provided with the assignment.•

In processing that data you’ll need to read each line using READLINE, or all into one list with READLINES• Since the data is comma-separated you’ll have to use the string ‘split’ method to separate the attributes (or fields) from each line and store each in a list.• Remember that all the input data will arrive in your program as a character string. To process the population data you’ll have to convert it to integer format.• The input fields have some extraneous spaces that will have to be removed using the string ‘strip’ method.• As each line is read and split, add an entry for it to the dictionary as described above.• Be sure to import ‘json’ and use the ‘dumps’ method to create the output string for writing to the file.• The visual inspection is for your benefit and won’t be reviewed or graded.• Use the ‘loads’ method to process the read json file data into a Python data structure.• Iterate through the dictionary and compare each state’s population to determine which to display. Be sure you’ve stored the population in the dictionary as an integer so you can do the comparison with 5,000,000.

To return all rows and columns with the correct commands in a basic select command, the following commands are used:SELECT *FROM table nameORDER BY column(s);

Explanation:

The SELECT command is used to choose columns from a table. The SELECT command may retrieve all columns or a subset of columns. It can also be used to get a single value from a specific column. For instance, if we want to get the value of a certain name column from a specific row, we would use the SELECT statement.

The "FROM" keyword indicates the table from which we will be retrieving data. This is because we are selecting data from a specific table. We must specify the table name in order to retrieve data from it.

The "ORDER BY" clause is used to sort data in ascending or descending order. When sorting data, we can choose to use one or more columns as the sorting criteria. This can be accomplished by listing the column names separated by commas.

The SELECT command is used in combination with the "FROM" clause to obtain data from a table. We can add a WHERE clause to the SELECT statement to filter data. The WHERE clause is used to filter the rows of a table.

The given statement, "Bits are encoded in a wave by precisely manipulating, or modulating, amplitude, frequency, or phase" is true.

Modulation is the process of changing one or more properties of a periodic waveform known as a carrier signal with information-bearing signal. The aim is to transfer the information through a channel, normally a radio channel or a communication wire, by allowing the carrier to vary its characteristics based on the modulating signal's variations.In the modulation process, the information or message signal is superimposed on the carrier wave. The three basic types of modulations are Amplitude Modulation (AM), Frequency Modulation (FM), and Phase Modulation (PM). In digital modulation, a number of digital symbols are transferred onto an analog waveform with digital signal processing (DSP) techniques.Bits are encoded in a wave by precisely manipulating, or modulating, amplitude, frequency, or phase. This is accomplished through a variety of modulation techniques. The modulated waveform is then transferred over a channel that can be affected by noise and distortion. The demodulation process extracts the original information from the modulated wave. The effectiveness of a modulation technique is judged on its efficiency in bandwidth and power usage, robustness to noise and distortion, and the complexity of implementation.
