42. 003333 seconds equals 300 signals sec ond If each signal carries a single bit the bit rate is 300 bps if each signal carries four bits the bit rate is 1200 bps The difference between bit rate and baud is very important It can be easily shown that transmission over ordinary telephone lines cannot exceed 6000 baud or so However the bit rate can be on the order of 30 000 bits per second These numbers are based on Nyquist s and Shannon s theo rems well beyond the scope of this article interested readers are referred again to McNamara or Stallings Parity is an error detection mechanism In an even parity system all characters must have an even number of one bits turned ON in an odd parity system an odd number of one bits must be ON Consider the seven bit ASCII characters A 1000001 and E 1000101 When parity is used these seven bit characters are transmitted as cight bit entities where the MSB or leftmost bit is the parity bit In an even parity system A with an even number of one bits already ON has the parity bit turned OFF thus it is sent as 01000001 The E on the other hand has an odd number of one bits so its parity bit is ON to make the number of one bits even thus E is sent as 1 1000101 In an odd parity system characters A and E are represented as 11000001 and 01000101 respectively see Figure 3 Two other types of parity systems can also be used In a MARK parity scheme the parity bit is always s
