In this video, we solve 8 important problems on Sampling, Nyquist Rate, PCM, and Signal-to-Quantization Noise Ratio (SQNR) that frequently appear in Communication Systems and Digital Communication exams.
Topics covered step-by-step include:
• Nyquist Sampling Rate calculation
• Sampling Theorem applications
• Signal Spectrum after Sampling
• Maximum Sampling Interval
• PCM storage calculations
• Signal-to-Quantization Noise Ratio (SQNR)
• Quantization Bits vs SNR
• Time Division Multiplexing (TDM)
• Transmission Bandwidth calculation
These solved examples are ideal for electronics engineering students, telecommunications students, and anyone studying digital communications.
Problems explained in this video:
1️⃣ Finding the Nyquist rate for different signals
2️⃣ Spectrum of a sampled signal and reconstruction filter
3️⃣ Maximum allowable sampling interval and number of samples
4️⃣ PCM storage capacity and recording duration on a USB drive
5️⃣ SQNR calculation for a PCM system
6️⃣ Sampling and multiplexing of multiple voice signals
7️⃣ Deriving SQNR for uniformly distributed signals
