The standard defining the ATR in asynchronous transmission is ISO / IEC 7816-3.
2.
Please how do i draw out a correlation between Baseband Transmission, Broadband Transmission, Asynchronous Transmission and synchronous Transmission.
3.
The link is based on character asynchronous transmission with 1 start bit and 1, 1.5 or 2 stop bits.
4.
The ATR in asynchronous transmission is precisely normalized ( in order to allow interoperability between cards and readers of different origin ), and relatively complex to parse.
5.
NRZ-Level itself is not a synchronous system but rather an encoding that can be used in either a synchronous or asynchronous transmission environment, that is, with or without an explicit clock signal involved.
6.
The 26C92 is an upwardly compatible version of the 2692, with 8-byte transmitter and receiver FIFOs for improved performance during continuous bi-directional asynchronous transmission ( CBAT ) on both channels at the maximum standard speed of 230.4 kbit / s.
7.
"' BLAST "'( "'BLocked ASynchronous Transmission "'), like XMODEM, is a communications protocol designed for file transfer over ANSI in the mid-80s as part of that organization's ultimately futile attempt to establish a single de jure standard.
8.
In asynchronous transmission, the ATR is transmitted by a card to a reader as characters, encoded as bits over the contact designated I / O ( C7 ), with a nominal bit duration denoted Elementary Time Unit ( ETU ), equal during the whole ATR to 372 periods of the clock signal supplied by the reader on the CLK ( C3 ) contact.
