kilometers away, in what we assume to be free space, in the direction of maximum gain. 1. How much power reaches the receiving antenna? 2. What is the EIRP in the direction of maximum transmitter antenna gain? 3. What is the power density around the receiving antenna? 4. What is the electric field intensity around the receiving antenna? 5. What is the path loss in free space in both ratio value and dB?
Suppose the voltage across a telephone line at the subscriber drops from 48V to 10V when the phone goes off hook. If the telephone instrument has a resistance of 200 ohms when off hook and represents an open circuit
An op-amp is to be selected for an inverting amplifier to be used at dc and very low frequencies. A closed-loop nominal gain of -100 is desired. Specification indicate that the error due to finite open-loop gain cannot exceed 0.1dB.
Titan has numerous hydrocarbon lakes containing a mix of methane and ethane in unknown proportions. A small submersible vehicle will exlpore Kraken Mare, the largest lake.
A half-wave rectifier circuit with a 1-k ohm load operates from a 120-V (rms) 60-Hz household supply through a 10-to-1 step-down transformer. It uses a silicon diode that can be modeled to have a 0.7-V drop for any current.
The current flowing into a particular capacitor is given by the expression I = 6e^(-0.05t) where I is in Amps and t is in seconds. The voltage across the capacitor during the same time period is given by V = 10-10e^(-0.05t) where V is in Volts.
electronic technology in relationship to the use of personnel and access control, surveillance, and identification of authorized personnel.
2. Design an amplifier with a gain of 2 using Multisim. 3. What is the phase shift between the input and output signals of an inverting op amp 4. What is the phase shift between the input and output signals of a non- inverting op amp
Determine the maximum raw instantaneous data rate that can be provided to a single user in EDGE, assuming that a single time slot on a single GSM channel is available.
Derive a state diagram for a Finite State Machine(FSM) that has an input w and an output z. The machine has to generate z = 1 when the privious four values of w were 1001 or 1111; otherwise, z = 0. Overlapping input patterns are allowed.
If the battery is replaced with a 6 Volt battery it was experimentally determine that the no load speed is reduced to 120 rpm. For this situation, determine a new equation for angular velocity,(in rad/sec) versus Torque (in Nm).
Determine the service overcurrent protection device rating and undergrounded and grounded service conductor size. Use XHHW copper conductor and 75oC device terminal ratings and allow for 25% load growth. Do not use larger than 600 kcmil conductor ..
