1. An analog information signal, whose maximum frequency is 6000Hz, is to be transmitted using a PCM system. The quantization error must not exceed the 1 % of the peak-to- peak analog signal.
(a) What is the minimum number of bits per sample or bits per PCM word that should be used in this system?
(b)What is the minimum required sampling rate, and what is the resulting bit rate?
(c)What is the PCM pulse or symbol transmission rate?
What is Capacitance - Capacitance is explained to be the amount of charge Q stored in among the two plates for a potential difference or voltage V existing across the plates.
Q. Methods for speed and torque control of induction motors? The following are methods available for speed and torque control of induction motors. • Pole-changing method
Explain priority interrupts of 8085. The 8085 microprocessor has five interrupt inputs. They are TRAP, RST .5, RST 6.5, RST 5.5, and INTR. These interrupts have a fixed prio
