Assume that a receiver has a first amplifier stage with a 5KW input resistance, a gain of 300, an input audio signal of 20 mV, and an operating temperature of 27oC. When the amplifier is operating with a bandwidth first of 10 MHz, finD:(a) the rms input noise levels (b) the audio output levels(c) the rms output noise levels
Suppose that the sequence 110010011 is used as a synchronization sequence preamble to a data packet. Propose a method that can be used to allow the channel to distinguish the synchronization sequence from an identical data sequence within the pack..
A tooling designer is designing a jig that will insert pins into the flip-up handles of a coffeemaker. The bin to hold the pins should hold enough pins for 3 hours' work before reloading. The engineering estimate for the rate of inserting the pins..

Consider a permanent-magnet dc-motor with the following parameters: Ra=0.35Ohms, La=1.5mH, Ke=0.5V/(rad/s), Kt=0.5Nm/A, and Jm=0.02kgm^2. The rated torque is 4Nm. This motor is supplies by a switch-mode dc-dc converter
Vary as square root-application, The frequency f of vibration of a wire varies directly as the square root of the tension T of the wire
Suppose a 12-V battery bank rated at 200 Ah under standard conditions needs to deliver 600 Wh over a 12-h period each day. If they operate at -10 Celsius, how many days of use would they be able to supply
A wind speed sensor generates an output voltage that ranges between 10 to 55 mV when the wind speed varies from 0 to 120Km/Hr.The output of the sensor is connected to an Analog to Digital Converter (ADC) through a signal conditioning circuit.
A terminated transmission line with Z0 = 60 ohm has a reflection coefficient at the load of = 0.4 60. (a) What is the load impedance (b) What is the reflection coefficient 0.3 away from the load (c) What is the input impedance at this point
Determine the minimum signal to noise ratio (s/n) in dB required in each communication channel to achieve a data rate of 270 kbps?
Devise a detailed algorithm for a ring with p nodes so that each node would atttain the final sum of original node values. Determine the worst case communication steps for the algorithm.
(b) This voltage is measured using a defective voltmeter, which always indicates a lower reading than the actual value. Suppose the voltmeter reading is 2.5*10^(-4). Calculate the probability that the error is not more than 0.5 *10^(-4).
The design must show all stages used in its development and must be implemented and tested in PSpice and suitable timing waveforms produced.
