To determine the minimum data rate and minimum bandwidth required to transmit the multiplex signal, we need to first determine the minimum sampling rate required to sample each of the telemetry signals. The Nyquist rate is defined as half the bandwidth of the signal, so the Nyquist rate for each telemetry signal is 120 Hz. To sample at least 20% above the Nyquist rate, we need to sample at a rate of at least 120 Hz * 1.2 = 144 Hz.
Since there are 5 telemetry signals, the total number of samples per second is 5 * 144 = 720 samples/s. Since the signals are being encoded using binary PCM, each sample will require 1 bit to represent it. This means that the minimum data rate required to transmit the multiplex signal is 720 samples/s * 1 bit/sample = 720 bits/s.
To determine the minimum bandwidth required to transmit the multiplex signal, we need to consider the bandwidth required for the 5 telemetry signals as well as the additional bandwidth required for framing and synchronization. The total bandwidth required for the telemetry signals is 5 * 240 Hz = 1200 Hz. The additional bandwidth required for framing and synchronization is 1200 Hz * 0.5% = 6 Hz. The total minimum bandwidth required to transmit the multiplex signal is 1200 Hz + 6 Hz = 1206 Hz.
The maximum pace of data flow along a particular path is referred to as bandwidth in computing. Network bandwidth, data bandwidth, and digital bandwidth are three different types of bandwidth.
Contrary to this definition, bandwidth is used to refer to analog signal bandwidth measured in hertz, which is the frequency range between the lowest and highest attainable frequency while meeting a well-defined impairment level in signal power in the fields of signal processing, wireless communications, modem data transmission, digital communications, and electronics.
The actual bit rate that may be obtained is influenced by the channel noise as well as the signal bandwidth.

The Linux family of open-source Unix-like operating systems is based on the Linux kernel, which Linus Torvalds initially made available on September 17, 1991. Linux distributions, which are how Linux is commonly packaged, frequently include the kernel and other system-supporting programmes and libraries, many of which are made available by the GNU Project. Although the Free Software Foundation likes to refer to their operating system as "GNU/Linux" to emphasise the importance of GNU software, many Linux versions have the term "Linux" in their names. This has caused some controversy. The most well-known Linux distributions are Debian, Fedora Linux, and Ubuntu. Lubuntu and Xubuntu are just two of the many distributions and modifications that make up Ubuntu.

a byte-addressable main memory of size 256mb with blocks of 32 bytes in size. the cache memory can hold up to 64 blocks
The main memory can hold a total of (256 * 1024 * 1024) / 32 = 8,388,608 blocks.
What are main and cache memory?he main memory in this system has a size of 256 megabytes, which is equal to 256 * 1024 * 1024 bytes. With blocks of 32 bytes in size, this means that the main memory can hold a total of (256 * 1024 * 1024) / 32 = 8,388,608 blocks.
The cache memory, on the other hand, can hold up to 64 blocks. This means that it can store a small fraction of the data that is stored in the main memory. In order to access data that is not stored in the cache, the system must fetch it from the main memory, which takes longer than accessing data directly from the cache.

What is an array?Using an entire set of values at once is possible with array programming, a technique used in computer science. These answers are frequently applied in scientific and engineering contexts. A data structure called an array consists of a set of elements (values or variables), each of which is identified by an array index or key.
Depending on the language, other data types that describe aggregates of values, like lists and strings, may overlap (or be identified with) array types. An array is a grouping of identically-typed elements that are stored in consecutive memory locations and can each be individually referred to using an index to a special identifier.
Based on the information, it should be noted that none of the code will return the same result as all the codes does not assign correct values to array.
Therefore, based on the information, the correct option is E.

you are using the vi editor to manage a text file on a linux system. you want to type new text into the file. when you type, you want the existing text that comes after the cursor to be pushed down.
The insert mode is used to type new text into the file in linux system.
What is insert mode in linux system?When inserting text into a file, you should be in insert mode. Command mode is the mode to be in when issuing commands such as moving the cursor, deleting text, copying and pasting, saving the file, and so on. Vi is in command mode when you open a file. Insert mode is required to enter text.In Insert mode, you can enter text, use the Enter key to move to a new line, navigate text with the arrow keys, and use vi as a free-form text editor. Press the Esc key once to return to Command mode.In vi, there are three modes of operation:
Mode of Command: When you launch vi, it is in Command Mode.Insert mode: You can insert text into the file using this mode.Last Line Mode (Escape Mode): While in Command Mode, type a colon [:] to enter Line Mode.The complete question:
