电文块报头48比特，电文最多1696比特，电文块CRC32比特的甚高频数据广播（VDB）数据链路层报文用数字信号格式具体举例

假设电文块报头为010101010101010101010101010101010101010101010101，电文内容为"Hello World!"，CRC32为11001010101110001111001110011111。

将电文块报头、电文内容和CRC32拼接起来，得到01010101010101010101010101010101010101010101010101001000010100000101101100011011110110111101101100011001010110000101101100011011000110010100100000 01011011011100110110010101110010011011110110111000100000 00110001001100010111000001110100011001010111001100100000 11001110011011110010110100100000

然后，将上述二进制串转换为数字信号格式，即将0转换为低电平信号，将1转换为高电平信号，得到以下数字信号串：

1010101010101010101010101010101010101010101010101010101010101010101010101010101010101010101000101000001011011000110111101101111011011000110010101100001011011000110110001100101001000000101101101110011011001010111001001101111011011100010000000110001001100010111000001110100011001010111001100100000110011100110111100101101001000000

这样，就可以通过数字信号的方式将电文广播出去。
