A fabric produces two kind of products, the product one of red color and product two of green color. Before the quality control they arrive through a conveyor belt in a random way. Through a system of image recognition a piston drives a separator that passes from position one to position two depending on the product. The conveyor belt moves relatively slow therefore several seconds pass before the separator switches position. The piston moves two switches (N/A) when it is on position one or on position two. The control system requires a variable exit voltage between 25 and 10 volts. Design a circuit that performs this function.
Suppose that you wish to offer a voice over IP wireless service. The target packet error rate (or drop rate) is 10^-3 and you determine that if the signal is confined to within a coherence band, about 20% of the packets are dropped due to fading.
The unit impulse response of an LTIC systems is h(t) = (1- 2t)e^-2t * u(t) Find this system's (zero-state) response y(t) if the input x(t) is: 1) u(t) 2) e^-t u(t) 3) e^-2t u(t) 4) sin(3t) u(t)
1. Point charges Q1 and Q2 are respectively, located at(4,0,-3) AND (2,0,1). If Q2=4nC, find Q1 such that a. E at (5,0,6) has no no z component b. The force on a test charge at (5,0,6) has no x component
Given the following circuit, in which R1 = 200 (Ohm), R2 = 100(Ohm), V1 = 6 V, and V2 = 3 V. Assume the diode turn-on voltage is 0.7 V. Find the current through the circuit. Find the voltage V1 for which the diode just starts to conduct.
Determine the output voltage for an op-amp comparator circuit with a non-inverting input reference voltage of + 2 VDC and an inverting input signal of - 1 VDC. The op amp reaches output saturation voltages of ±13 V at the limits.
the saturated liquid and vapor mixture at t=300c and quality of 75%.the mixture occupies a volume of 0.05 m^3 (a) find the specific volume in m^3/kg (hints: vf= 0.0014 vg=0.02167m^3/kg at t =300c) (b) find the mass of the mixture in kg.

The 300-kg block is acted upon by a force P, pulling it as shown. P makes an angle of 36o with the horizontal. If the coefficient of sliding friction between the block and the floor is 0.35, determine the force required to start moving the block.
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..
