Question

The American Standard Code for Information Interchange (ASCII) has 128 binary-coded characters. A certain computer generates data at 1,000,000 characters per second. For single error detection, an additional bit (parity bit) is added to the code of each character. What is the minimum bandwidth required to transmit this signal.

Answer 1

Answer:

350 kHz

Explanation:

as there are 100,000 character per sec.

so, total number of bits per sec = 100,000 * n

= 100,000 * 7 = 700,000 bits per sec

= 700 kbps

Bandwidth (BW) = total no. of bits / 2

BW = 700 kbps/2

= 350 kHz
