Select the TOOLS menu and then WORD COUNT. A dialogue box will appear containing the character count. Let the selection of Q and Q bar output of the preceding FF be controlled by the mode control input M such that, If M = 0, UP counting. So connect Q to CLK. If M = 1, DOWN counting. So connect Q bar to CLK. The counter will be updated instantly, displaying the amount of characters, words, sentences, paragraphs and whitespace in your text, not to mention that the keyword density (which you can configure from the options menu) is also displayed.

The 74LS47 has four inputs for the BCD (8-4-2-1) digits A, B, C and D, and outputs for each of the segments of the seven-segment display.

Multiplication rounding and division rounding is performed based on the number of significant figures in the measurement with the lowest count of significant digits. For example, multiplying 20.0 by 10 will result in 200. Since only a single digit ("1") is significant in the second number rounding to the first significant digit gives us 200 of which only the "2" is significant. In another example, let us say we multiply 2.5 by 10.05 and get 25.125. Since 2.5 has only two significant digits, we must round the result to two significant digits as well, giving us an answer of 25. This rounding rule is applied automatically in our tool. LibreOffice 4 displays the character count in the status bar at the bottom of the program, along with the word count. For a detailed character count, select the TOOLS menu and then WORD COUNT. A dialogue box will appear containing the character count. Select the REVIEW tab. Select WORD COUNT from the box labeled PROOFING. A dialogue box will appear containing the character count. The Q outputs then represent a four-bit binary count with Q 0 to Q 3 representing 2 0 (1) to 2 3 (8) respectively. A practical example of these devices is seen in malls, stadiums, or auditoriums. In the above situations to keep the data on the number of persons. This can be made possible or it will become simple because of these counters.

The rule for adding significant figures is to round the result to the least accurate place. The sum or difference is to be rounded to the same number of decimal places as that of the measurement with the fewest decimal places which reflects the fact that the answer is just as precise as the least-precise measurement used to compute it. For example, 2.24 + 4.1 = 5.34 which has to be rounded to one place after the decimal dot, since 4.1 is only precise to that level, giving a result of 5.3. If we were adding 2.24 and 4.10 though, the result would be 5.34. Our significant figures calculator uses this rule automatically. You can choose if the rounding is done using the half away from zero rule or by the half to even rule. The rule for adding is also used for subtraction of numbers with a given number of significant digits. Significant figures multiplication rule

here the trailing zero is significant as it is to the right of the decimal point, while the other zero is also significant since it sits between two significant figures: the seven to the left and the zero beyond the decimal point Numbers are often rounded to a specified number of significant figures for practicality, e.g. to present in a news broadcast or to put down in a table neatly. Rounding a number to n significant figures happens in a similar way to rounding to n decimal places, with an important difference. We start by counting from the first non-zero digit for n significant digits and then round the last digit. However, we do not fill in the remaining places to the right of the decimal point with zeroes. While an LED segment can be illuminated individually as required, one terminal of each internal LED is connected to a common point or node. Thus instead of having 14 connecting pins for the display we will only have only eight (7 + 1) pins, one each for the seven individual LEDs plus a common pin, and it is this “common pin” which identifies the type and name of 7-segment display. In the current and modern society, letters come in all forms. We use letters to communicate with other people anywhere in the world. In business, employees create business letters at one point in time, and include counting the characters. To simplify things, the users utilize software to type the document and count the number of words and characters they use. Another way to count the number of characters or words in letters is through a character counter online. This type of Large Digit LED COUNTER is also called a BATCH COUNTER, whereby a preset value is entered and then the counter is activated by input signal to count down from this value to ZERO or another preset value.

You can copy and paste your text with the characters to count in the text area above, or you can type your characters and words into the text area. These counter circuits are the basic ones in the ‘Digital Electronics’. These counters possess various applications. So if a 7-segment display consists of seven LED’s (ignoring the decimal point for now), one for each segment, and an LED has two terminals, an Anode and a Cathode, does that mean that each single 7-segment display will have 14 connecting pins or terminals. Well the answer is, No. the first two zeroes are between significant digits greater than zero, the third zero is also significant since it is both to the right of the decimal point and is between two significant digits Modifications such as those described in this module make the basic synchronous counter much more versatile. Both TTL and CMOS synchronous counters are available in the 74 series of ICs containing usually 4-bit counters with these and other modifications for a wide variety of applications. Fig 5.6.15 shows how all the input functions described above, plus some important outputs such as Ripple Carry (RC) and Terminal Count (TC) can be combined to form a single synchronous counter IC.

Synchronous BCD Up Counter

CE (Count Enable) - Allows the count to proceed when at 0. Stops count without resetting when at logic 1. Operation of four switches S A, S B, S C and S D, will generate the necessary input sequence to activate the appropriate LED segments responsible for displaying the corresponding number. For normal operation, the LT (Lamp test), BI/RBO (Blanking Input/Ripple Blanking Output) and RBI (Ripple Blanking Input) of the 74LS47 are all connected to the +5V supply (HIGH). Thus the numbers displayed are as follows: 7-segment Display Numbers These connections are same as those for the normal up counter. Thus with M = 0 the circuit work as an up counter.

However it is also sometimes possible to obtain a charactercount using your text editing software.
