Question

С помощью алфавита из 32 символов в течение 5 минут передавалось сообщение со скоростью 20 килобит в секунду надо найти объем информации и количество переданных символов

Answer 1

32-х символьный алфавит кодирует один символ 5-ю битами $N=32=2^b=2^5$

5 минут = 300 секунд

передалось = 300 секунд * 20 кбит/с = 6000 кБит

передалось = 6000 кБит / 5 бит/символ = 1200 символов

Answer 2

Calculating Information Volume and Number of Characters Transmitted

To calculate the volume of information and the number of characters transmitted, we can use the formula:

Volume of Information (in bits) = Transmission Speed (in kilobits per second) * Time (in seconds)

Given: - Transmission speed: 20 kilobits per second - Time: 5 minutes (or 300 seconds) - Alphabet with 32 characters

Let's calculate the volume of information and the number of characters transmitted.

First, we calculate the volume of information: Volume of Information = 20 kilobits/second * 300 seconds = 6000 kilobits

Next, we calculate the number of characters transmitted: Number of Characters = Volume of Information / Bits per Character

To find the number of bits per character, we can use the fact that the message was transmitted using an alphabet of 32 characters. This means each character can be represented using 5 bits (since 2^5 = 32).

Number of Bits per Character = log2(32) = 5 bits

Now, we can calculate the number of characters transmitted: Number of Characters = 6000 kilobits / 5 bits per character = 1200 characters

So, the volume of information transmitted was 6000 kilobits, and the number of characters transmitted was 1200 characters.
