To calculate the actual bit string transmitted using the CRC method with generator polynomial 1001, we need to follow these steps:
1. Append 3 zeros to the end of the bit stream to create the dividend: 10011101000
2. Divide the dividend by the generator polynomial using modulo-2 division (XOR operation) and obtain the remainder.
```
____________
1001 | 10011101000
1001
------
1100
1001
----
111
100
---
110
100
---
101
100
---
10
```
3. The remainder obtained is 10, which is appended to the end of the original bit stream to create the actual bit string transmitted: 1001110110
Therefore, the actual bit string transmitted is 1001110110.
