(a) Describe the possibilities of limiting a digital signal - i.e. a bit pattern - in frequency before modulation and transmission.
(b) How can overlapping by adjacent pulses (interference) be limited?
(c) How is it possible to determine qualitatively using measuring techniques whether the information of a received signal can be reconstructed?
(d) Why are many filter types not suitable for filtering "rectangular" bit sequences?
A serial input finite state machine has one input and one output. The output becomes 1 and remains 1 thereafter when at least two 0's and at least two 1's have occurred as inputs, regardless of the order of occurrence. Draw a state diagram for the..
Assume that there is a flip-flop with the characteristic given in Figure P14.13, where A and B are the inputs to the flip-flop and Q is the next state output. Using necessary logic gates, make a T flip-flop from this flip-flop.v
What is the symbol rate of the earth station transmissions? What is the bit rate of the earth station transmissions? What is the duration of the burst transmission from each earth station?
An amplifier has three stages A,B and C of voltage gains 200, 300 and 400 respectively.find the overall gain in ratios
The fundamental to an understanding of EMC are the concepts of differential mode, common mode and antenna mode radiated field coupling. Describe the differences between differential mode and common mode coupling. How does it apply to both emissio..
A plane electromagnetic wave of frequency 300 MHz propagates in homogeneous sea water (ε=80,σ=1) along the z-axis. The effective field strength at the excitation point(point of origin) is 0.1V/m.
Paint manufacturer is studying two different paint formulas
A 100V dc series motor has an armature resistance of 0.2 ohm and field resistance of 0.25 ohm. The motor runs at a speed of 600 rev/min when the shaft torque is 27.14 Nm. Friction and windage losses at this speed are 300W.
Using D-type flip-flops, design a synchronous Moore finite-state machine that monitors two inputs A and B, and asserts a scalar output if the number of 1s observed on the inputs is a multiple of 4.
a machine processor address a maximum 2^24 bytes of memory. What is the maximum number of 32 bit words that can be store in memory.
a) Find the value of the voltage source "E"that is required to provide a 10V across the 10kΩ resistor. What are the values of [V10k/E] and [V3.3k/V10k] b) Dtermine the amount of power supplied by the voltage source when E= 20V.
Find the longest allowable evaluate time if the decay in output voltage is to be limited to .2V. If the precharge interval is much shorter then the maximum allowable evaluate time, find the minimum clocking frequency required.
