1. Design a driven.right.leg circuit, showing all resistor values. For 1 microamp of 60 Hz current flowing through the body, the common -mode voltage should be reduced to 2 mV. The circuit should supply no more than 5 mkroamp when the amplifier is saturated at 13 V.
2. In the given figure Zin r 2 Mohm, 21 = 25 kohm, Z2 v 10 kohm, idb 5 500 nA, & ZG = 40 kohm. Calculate the power line interference.
3. Design a bandpass filter with cutoff frequencies of 1 & 40 Hz. This can he synthezied with a LP & HP filters.
4. Calculate Vo in the given figure.
5. What are the methods to eliminate noise when making ECG measurements.
A shunt DC motor has RA = 0.7-ohm and VT =429.6 V. For an output power of 50.4 hp, we have nm = 1,452 rpm and IA = 110.8 A. The field current remains constant for all parts of this problem. Find the rotational power loss in watts.
At the receiver, the carrier is reinserted during demodulation, but its frecuency is 5.00015 MHZ rather than exactly 5 MHZ. How does this affect the recovered signal How would a voice signal be affected by a carrier that is not exactly the same as..
A proportional control system is to be used to control the wing flap of a jet airplane. The wind load is expected to cause as much as 600 in-lb of torque. The system should be able to keep the flaps with 5o of the set point.
Consider a receiver that consists (in the sequence) of the following components: (i) an antenna connector and feedline with an attenuation of 1.5 dB; a low-noise amplifier with a noise figure of 4 dB and a gain of 10 dB, and a unit gain mixer wit..
Design an amplifier for a power gain of 15dB at 3 GHz if 1. Plot the input and output constant-Gain circles. 2. Find the input and output matching networks. use L C components.
What is a Solenoid and Solenoid Magnetic Field ?
what is the perceived colour if you mix red ,green and blue dyes in equal proportion and why What about red and green frequiencies only
1) Use the following function g(a,b,c) = (a'+b)(b'+c) for parts (a)-(d) below. a) write g as a minterm LIST b) write g as a canonical sum-of-products c) write g as a maxterm LIST d) write g as a canonical product-of-sums
An LVDT is used in an accelerometer to measure seismic-mass displacement. The LvDT and signal-conditioning output is 0.31 mV/mm with a +/-2 cm maximum core displacement. The spring constant is 240 N/m, and the core mass is 0.05 kg.
A 450 kW motor operating 73% Power factor lagging is connected to a 120V(rms), 60Hz line. (a) Sketch and label the power triangle for the motor. (b) Find the rms current into the motor.
A shunt regulator utilizing a zener diode is biased on through a 100-ohm resistor. Determine the change in the regulated output voltage for the two situations below: a) VI changes +2.0 V, ILoad constant b) ILoad changes +100 mA, VI constant
Design a second-order band-pass filter for a system with sampling frequency of 18 kHz that is tuned for f=5kHZ The filter should not have any sample delay (the numerator and denominator orders are equal) and should have a stability margin of 92%.
