Signal

 Signal Strength: One way to evaluate the performance of a cellular network is to measure the signal strength at various locations. This can be done using tools such as signal meters or by simply observing the signal bars on a mobile phone. A strong signal indicates good coverage, while a weak signal may indicate areas where the network needs improvement.


Data Speeds: Another way to evaluate a cellular network is to measure the data speeds it provides. This can be done using speed test apps or by downloading files of known sizes and measuring the time it takes to download them. Faster speeds generally indicate better network performance.


Call Quality: Evaluating the quality of calls made over a cellular network is also important. Factors such as call drops, voice clarity, and call setup time can be used to determine the overall call quality.


Coverage Area: Evaluating the coverage area of a cellular network can also be useful. This involves measuring the signal strength and data speeds at various locations to determine the extent of the network's coverage.


User Experience: Ultimately, the user experience is one of the most important factors in evaluating a cellular network. This can be measured through surveys and feedback from users, as well as by tracking customer complaints and resolution times.

1G: The first-generation cellular network (1G) was introduced in the early 1980s, and it used analog signals for communication. It had low voice quality, limited coverage, and security issues.


2G: The second-generation cellular network (2G) was introduced in the 1990s, and it used digital signals for communication. It improved voice quality and introduced new features like text messaging, call waiting, and caller ID.


3G: The third-generation cellular network (3G) was introduced in the early 2000s, and it offered faster data speeds, video calling, and mobile internet access.


4G: The fourth-generation cellular network (4G) was introduced in the late 2000s, and it offered even faster data speeds, improved voice quality, and better coverage. It also introduced features like VoLTE (Voice over LTE), which allowed voice calls to be made over the internet.


5G: The fifth-generation cellular network (5G) was introduced in the late 2010s, and it offers faster data speeds, lower latency, and improved network capacity. It also supports new technologies like augmented reality and autonomous vehicles.

HEXADECIMAL NUMBER SYSTEM CONVERSION

 HEXADECIMAL NUMBER SYSTEM CONVERSION           1.HEXADECIMAL NUMBER CONVERSION Number System with base value 16 is termed as Hexadecimal Number System. It uses 16 digits for the creation of its numbers. Digits from 0-9 are taken like the digits in the decimal number system but the digits from 10-15 are  represented as A-F i.e. 10 is represented as A, 11 as B, 12 as C, 13 as D, 14 as E, and 15 as F. Hexadecimal Numbers are useful for handling memory address locations. * HEXADECIMAL NUMBER SYSTEM TO BINARY NUMBER SYSTEM; Hex numbers are represented in base 16, but the binary numbers are of base 2. Hence, to convert a hexadecimal number to a binary number, the base of that number is to be changed. Follow the steps given below: Step 1:  Convert the Hex symbols into its equivalent decimal values. Step 2:  Write each digit of the Hexadecimal number separately. Step 3:  Convert each digit into an equivalent group of four binary digits. Step 4:  Combine these groups to form the whole binary n

CONONOCAL FORMS

Image
CANONICAL FORMS  Two dual  canonical forms of any  Boolean  function are a"sum of min terms " and a "product of max terms."             The term "Sum of Products" (SoP or SOP) is widely used for the  canonical form  that is a dis junction (OR) of min terms.               The  SOP  (Sum of Product) and   POS  (Product of Sum) arethe methods for deducing a particular logic function. ...                      The prior difference between the  SOP and POS  is that the  SOP contains the OR of the multiple product terms. Conversely,  POS produces a logical expression comprised of the AND of the multiple OR terms.        SOP Vs POS       CANONICAL FORMS OF SUM OF PRODUCT :                 Canonical  SoP form  means  Canonical  form  of Sum of Products.  In this  form , each  product  term contains all literals. So, these  product  terms are nothing but the min terms.Hence,  canonical  SoP  form  is also called as  sum  of min terms  form .       CANONICAL FORM OF

Maurice Karnaugh introduced it in 1953[1][2] as a refinement of Edward W. Veitch's 1952 Veitch chart,[3][4] which actually was a rediscovery of Allan Marquand's 1881 logical diagram[5] aka Marquand diagram'[4] but with a focus now set on its utility for switching circuits.'[4] Veitch charts are therefore also known as Marquand–Veitch diagrams,'[4] and Karnaugh maps as Karnaugh–Veitch maps (KV maps).           An example Karnaugh map. This image actually shows two Karnaugh maps: for the function ฦ’, using minterms (colored rectangles) and for its complement, using maxterms (gray rectangles). In the image, E() signifies a sum of minterms, denoted in the article as {\displaystyle \sum m_{i}}{\displaystyle \sum m_{i}}. The Karnaugh map reduces the need for extensive calculations by taking advantage of humans' pattern-
