encoded with an 8-bit PCM code. UPNRZ encoding is used. Determine: The line data rate (32)(8000)(8)=2.04mbps Minimum sampling rate =2(4khz)=8khz Minimum Nyquist bandwidth UPnRZ= Fb= 2.04mbps Consider a PCM-TDM system in which 24 signals are to be processed. Each signal has a baseband bandwidth of 3 KHz. The sampling rate has to be 33.3% higher than the theoretical minimum‚ and 8 bits are to be used. Conventional NRZ-L encoding format is used. An extra bit is added to each frame for sync. Determine:

Beginning Vibration Analysis with Basic Fundamentals By: Jack Peters Beginning Vibration Introduction Understanding the basics and fundamentals of vibration analysis are very important in forming a solid background to analyze problems on rotating machinery. Switching between time and frequency is a common tool used for analysis. Because the frequency spectrum is derived from the data in the time domain‚ the relationship between time and frequency is very important. Units of acceleration‚ velocity

between Digital and Analog Signals: Data communication is used every day to deliver data to external devices. Digital and analog signals are both still used for standard phone lines‚ but analog signals are now almost non-existent in households. Today digital signals are definitely more widely used over analog because the amount of people who use cell phones over standard telephones. Analog provides richer quality sound over digital‚ but digital has better clarity. An analog signal is continuous‚ but a

single peptide to enter the ER lumen and be cleaved by signal peptidase‚ the prolactin nascent chain must be 130 codons. The mRNA at size 130 codons in length is seen to have cleavage in the presence of microsomes. The shorter sized mRNA’s in the presence of microsomes‚ are the non cleaved residue peptides in which the signal peptidase is unable to cleave the signal sequence amino acid. B. Band B is the cleavage of the signal sequence by the signal peptidase. The cleavage of the polypeptide weighs
