<p><font face="Verdana">IF the 2T pulse is cos2-shaped, it has significant spectral components up to and<br/>above 8 MHz. Since according to ITU-R BT. 470 the bandwidth of the B/G system<br/>standard is 5 MHz, or pursuant to ITU-R BT. 601 a sampling rate of 13.5 MHz is<br/>used - yielding a maximum bandwidth of up to 6 MHz - symmetrical pre- and<br/>postshoots of up to 1.3% will result according to the standard.<br/>If nevertheless the cos2 signal is required, it can be generated at any time by SAF<br/>and SFF with the aid of the SIGNAL EDIT menu:<br/>After calling up SIGNAL EDIT, select the signal element MOD. PULSE.<br/>This element can be modified</font></p>
