एक निरंतर सिग्नल (continuous signal) की वोल्टेज सीमा −4 V से +2 V है। यदि इस सिग्नल को 8 बिट्स का उपयोग करके क्वांटाइज़ किया जाता है, तो क्वांटाइज़र का स्टेप साइज़ क्या होगा?

In a coherent M-ary system, the phase difference between symbols plays a crucial role in representing information. Compared to coherent binary phase shift keying (BPSK), what potential advantage does a coherent M-ary scheme offer?

If the binary sequence '1100' is encoded using the NRZ-L (Non-Return-to-Zero Level) encoding method, how many signal level transitions occur within the sequence duration (excluding the initial transition at the start of the first bit)?
