Character Error Rate Calculator for Text Telephony
- Number of milliseconds represented by each packet.
- Approximate number of milliseconds required to transmit a single character. For example, Baudot takes approximately 160ms to transmit a character.
- Number of redundant encodings, such as packets, according to RFC 2198.
- To update results, move to another parameter field,
e.g., by tabbing, or simply press the Update results button.
- Packet requirement is dislayed at full precision.
However, the other results are displayed with no more than two non-zero digits in the fractional part since this is a gross measurement.
- Number of packets transmitted per second.
- Number of packets required to form a complete character.
- Character error rates above 1% are considered unacceptable.
- When character time is less than packet time, this equation is superceded by the effective loss, thus quantizing the character error rate.
