1) Design an electrocardiograph with an input-switching system suchthat we can record the six frontal-plane leads by means of changingthe switch.2) An ECG lead is oriented such that its electrodes are placed onthe body in positions that pick up an electromyogram from the chestmuscles as well as the electrocardiogram. Design a circuit thatseparates these two signals as well as possible, and discuss the limitations of such a circuit.
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..
A temperature transducer has the relationship R=200 + 10T where R is in ohms and T is in Celsius. The problem specifications are: Range is 30=T=50°C Resolution is 0.01°C Frequencies of interest are 0 to 100Hz Transducer dissipation constant is 20 mW..
You are to design a Gray code sequence generator.The 4-bit Gray-code sequence is defined as follows: 0000, 0001,0011, 0010, 0110, 0111, 0101, 0100, 1100, 1101, 1111, 1110, 1010,1011, 1001, 1000.
The battery has 2.5 V output voltage and 12 Ohm internal resistance. The battery is used to boot a small electric motor with 145 Ohm resistance. Find the power delivered to the motor.
Desired D.C. Output : 10 V Load Variation: 0.3 kilo-ohms - 10 kilo-ohms Ripple Factor: Less than 0.1% for 2 kilo-ohms load Load Regulation: Better than 3 mV for a 1 mA change in load current
A sequence of 10 bits is transmitted over a binary symmetric channel with bit error probability Pe. Assume that bit errors occur independently. The sequence is considered to be received in error if more than two bit errors occur.
Amplifier with input resistance of 100k Ohm, an open circuit voltage gain of 100 V/V and output resistance of 100k Ohm is connected between a 10k Ohm signal source and 1k Ohm load. Find the overall voltage gain Gv and also find the current gain
a salient pole 60 Hz synchronous motor with a squirrel cage winding on the rotor which is used for starting purposes. (a) What is the frequency of the current in the squirrel cage rotor conductors immediately after the motor is energized (The motor..
For the signal x(t) = 4cos(800p t +p / 4) + 8cos(1200p t -p / 3) - 4cos(1600p t) : (a) Sketch the double--sided spectrum of the signal, indicating the magnitude and phase of each component. (b) What is the period of x(t)
Alice passes through four traffic lights on her way to work, and each light is equally likely to be green or red, independent of the others. Let X be the number of red lights that Alice encounters. Let A be the event that the first light is red.
A wire is stretched between two posts. Another wire is stretched between two posts that are twice as far apart. The tension in the wires is the same, and they have the same mass. A transverse wave travels on the shorter wire with a speed of 281 m/..
