Assertion (A) : The signaling rate and transmission channel bandwidth ...
Since, the delta modulation transmits only one bit for one sample, therefore the signaling rate and transmission channel bandwidth is quite small for delta modulation compared to PCM, Hence, assertion is a false statement.
The transmission and receiver implementation is very simple for delta modulation since there is no A/D converter required in delta modulation unlike PCM. Hence, reason is a true statement.

Delta Modulation and PCM
Delta modulation and Pulse Code Modulation (PCM) are two methods used for analog-to-digital conversion in communication systems. Delta modulation is a simpler form of analog-to-digital conversion compared to PCM. In delta modulation, the signal is sampled at a fixed rate, and the difference between the actual signal and the corresponding quantized signal is transmitted. On the other hand, in PCM, the analog signal is quantized and encoded into binary code before transmission.
Signaling Rate and Transmission Channel Bandwidth
The signaling rate refers to the number of signal changes per second, while the transmission channel bandwidth is the range of frequencies that can be transmitted without significant attenuation. The signaling rate and the transmission channel bandwidth determine the amount of information that can be transmitted over a communication channel. The higher the signaling rate and the transmission channel bandwidth, the more information can be transmitted.
Assertion and Reason
Assertion: The signaling rate and transmission channel bandwidth are quite large for delta modulation compared to PCM.
Reason: There is no analog to digital converter required in delta modulation unlike PCM.
Explanation
The assertion is false, and the reason is true. Delta modulation has a lower signaling rate and a smaller transmission channel bandwidth compared to PCM. This is because in delta modulation, only the difference between the actual signal and the quantized signal is transmitted, which results in a smaller bandwidth. However, PCM requires the transmission of the entire quantized signal, resulting in a larger bandwidth. The reason given in the statement is true because delta modulation does not require an analog to digital converter, making it simpler and less complex than PCM.
Conclusion
In conclusion, the assertion and reason given in the statement are incorrect. While delta modulation is a simpler form of analog-to-digital conversion compared to PCM, it has a lower signaling rate and transmission channel bandwidth. The reason given in the statement is true, but it does not explain the assertion.
