Suppose we have a sensor, with a Thévenin resistance that varies from zero to 10kΩ, connected to the input of an amplifier. We want the output voltage of the amplifier to vary by less than 2 percent with changes in the Thévenin resistance of the sensor. What parameter of the amplifier is important in this situation? What range of values is allowed for the parameter?
A pn-junction is formed in silicon by doping one side with acceptor atoms at concentration Na = 10^19 cm^(-3) and another side with donor atoms at Nd = 10^18 cm^(-3). A. What is the dopant concentration on the p-type side and on the n-type side
A 160-ft-diameter parabolic antenna is driven by a 10-W transmitter at 4.3 GHz. Calculate its effective radiated power (ERP) and its beamwidth.
The binary-coded-decimal (BCD) format uses 4 bits to represent 10 decimal digits. For example, 259 in base 10 is repesented as "010 0101 101" in BCD format. A BCD incrementor adds 1 to a number in BCD format.
The load requires 2 hp. If the dc-to-ac converter has a power efficiency of 88 percent and the motor has a power efficiency of 80 percent, estimate the current taken from the dc source.
Create a state diagram for an FSM describing this sequencing behavior, having aninput bit B, and two output bits s1 and s0. Be sure to onlysequence forward by one item each time the button is pressed,regardless of how long the button is pressed-in..
the magnetic circuit shown with a mean core length of 52 cm and a cross sectional area of 18 cm2. the length of the
The amount of heat Q needed to turn a mass, m, of room temperature ( T_1) water into steam at 100 Celcius. ( T_2) can be found using the specific heat, c, of water and the heat of vaporization, H_v, of water at 1 atmosphere of pressure.
In an electricity experiment, it was observed that as the potential difference in volts across a thin platinum wire increases the current in amperes changes as follows: (V,I)=(0,0), (1.0,0.112), (3.0,0.337), and (6.1,0.675).
design a circuit using an inverting amplifier that will produce a +- 10-V output signal corresponding to the bed position and deliver it to a 1k load. The output should be 0V at when the bed is in the center position
Problem 1: Consider the following Wheatstone bridge:
(a) Find the slip at the maximum developed torque. (b) If we would like to get the maximum torque at starting (s=1), a method is to add more resistance to the rotor, R2,new=R2,old + Rextra, while the rotor reactance X2 stays the same.
Audio data is stored in digital form on a DVD or CD and this data is converted back toanalog form by passing the digital data to a Digital to Analog(D/A) converter. What is the number of bits of resolution that is typically used in consumer audio ..
