An AM transmitter radiates 9 kW of power when the carrier is unmodulated and 10.125 kW when the carrier is sinusoidally modulated. Find the modulation index, percentage of modulation. If another sine wave corresponding to 40%modulation is transmitted simultaneously, then calculate the total radiated power.
Dynamic RAM that must be given a refresh cycle 64 times per ms. Each refresh operation requires 150 ns. memory cycle requires 250 ns.
Can you confirm-The outputs of two"NAND" gates are connected to the inputs of an "EXCLUSIVE OR" gate.Each of the "NAND" gates has one input at logic high level and the other input
Design a load resistor (resistance rating and power rating) network to have the transformer operate at full load. Design a second network for half load. You may need to combine several resistors to get the desired value.
8. What is Mac OS X's present day file system A) Macintosh Filing System (MFS) B) Hierarchical Filing System (HFS) C) Hierarchical Filing System Extended (HFS+) D) Extended File System (EXT) Th..
A byte containing 01100011 is right shifted (right-most bit first) into an 8-bit shift register with an initial state of 00110110 (01100011=>00110110) What does the shift register contain after three clock pulses
Phosphorous is an n-type dopant in Si since it introduces extra electrons to Si (an P atom has 1 more valence electron than Si). It is widely used in making semiconductor devices (p-n junctions for example).
A 1000 turns wire are tighly wound on a toroid with a rectangular cross section, the heigh of toroid is 0.5 cm . The inner and outer radii of 2 cm and 3cm respectively. The current in the wire I=100 mA, Ur = 4000. N= 1000, Find H,B,phi and inducta..
(1) How much power is dissipated by a 2.4 k resistor in series with a 12V power supply (2) Determine the result of dividing the squares of 12V by 3.3 k ohms.
Determine whether the following signals are periodic. If they are, find the smallest periods (fundamental periods). a) f(x,y) = sin (2 pi x) cos(4 pi y) b) Discrete signal: f(m,n) = sin ( pi * m / 5) cos(pi * n / 5)
Write the logic equation for Y in terms of A,B,C that solves this problem, and draw the gate-level diagram.
a 60-kHz sinusoidal signal is applied to an amplifier with a gain of k=2. the circuit is built with an lm741 opamp with power supplies +-13V. find the largest amplitude the signal may have before it is limited by slew rate constraints.
