a signal franging from 1khz to 100khz will be put into a davice that will need amplification that will output to speakers. A 12v battery is available as a power source, however the current out of the battery should be kept to a minimum. This 12v source will be in series with a 10 ohm resistor. Design a circuit using a limited number of components to achieve.
Consider a satellite communication link with a one way propagation delay of 300ms between the sender and receiver, operating at 10Mbps using packets of length 1500bytes. Length of the ACK packet is also 1500 bytes.
The base class must also have a virtual print() function that displays the class name. Randomly assign print functions in three other classes that display the class name. Create 7 pointers of the base class and have them point to all the classes.
The line is terminated in a load RL = 25 ohm. Use the bounce diagram to plot V(t) at a point midway along the length of the line from t = 0 to t = 25 ns.
A network router connects multiple computers together and allows them to send messages to each other. If two or more computers send messages simultaniously, they collide and the messages must be resent. Design a collision free circuit for a router..
You want to download a 5 Mbit file over a 10-Mbps Rayleigh fading channel in the 1800 MHz frequency band. You are traveling at 6 km/h and use 1000-bit packets.
Write the VHDL PROCESS statements for a D flip-flop with synchronous active-LOW clear, synchronous active-LOW preset, and responsive to a rising edge clock.
A) Design a low-pass filter with a cutoff frequency of 12 kHz. Use 0.15 uF capacitor and an appropriate resistor. B) Sketch and label the circuit. C) What is the gain of the filter at a frequency of 20 kHz Give your answer both as ratio (Vout/Vin) an..
The following test data were obtained from testing a 48kVA, 4800/240-V, step down transformer: Open-circuit test Voltage (V) 240 Current (A) 2 Power (W) 120 Short-circuit test Voltage (V) 150 Current (A)10 Current
Determine the value of the output voltage due to the voltage source only (Vol), and due to the current source only (V02).
A lamp of 100 candela is placed 1 m below a plane mirror which reflects 90% of light falling on it. The lamp is hung 4 m above ground. Find the illumination.
A 3.3V, 30 A dc power supply is to be designed with a ripple of less than 2.5%. Assume that a half-wave rectifier circuit (60 Hz) with a capacitor filter is used.
Restricting yourself to nondegenerate dopings and also requiring the resistance to be readily measured with a hand-held multimeter (say 1 R 1000), what is the range of doping Pick a doping concentration in the mid range.
