You have a 10 meter length of .5 cm diameter Nichrome wire. A24 VDC voltage is to be applied to it. The initial wire temp is 70degF. The final wire temp is 200 degF. What ids the initial currentand what is the final current?
A two-wire air line has the following line parameters: R = 0.404 (m/m), L= 2.0(µH/m),G= 0, and C= 5.56 (pF/m). For operation at 5 kHz, determine (a) the attenuation constant a,(b)the phase constant ß, (c) the phase velocity u,
A half-wave dipole antenna in a PCS handset at 1.9 GHz, requires a signal strength of 0.01 micro volts per centimeter to operate with acceptable performance. The transmit antenna is assumed to be a half-wave dipole, has a cell radius of 5 km.
use a third-order low pass filter with a -3dB frequency of 10 Hz to filter your signal. What sampling rate should you use to make sure any potentially aliasing frequencies are attenuated by at least -40 dB for a. A butterworth filter
Describe the operation of the transmission gate. Consider the source and drain terminals of both the NMOS and PMOS devices. Why not use two NMOS devices Does it pass analog or digital signals
A stack controller is a digital circuit in a computer that implements last in firstout (LIFO) storage for temporary data. It operates analogously to a stack of plates where you can put a new plate on the top of the stack or you can take a plate of..
Suppose that a voltage given by v(t) = 45 sin(100pt- 70°) is applied to a 9 O resistance. Sketch v(t) to scale versus time (make sure to put the labels on graph). Find the rms value of the voltage.
show that the resistivity of intrinsic Ge at 300k is 44.44 ohm-cm. If donor impurity is added to an extent of 1 atom per 10^8 Ge atoms, prove that the resistivity of the Ge sample drops to 4.42 ohm-cm (at 300k).
A pn junction diode is forward biased by a Thevenin circuit consisting of Rth = 5kohm and Vth = 10sinwt where w= 2pi*10rads/s. Find the diode voltage and current as functions of time.
Draw a circuit that shifts cyclically a register to left or toright ans is also able to preserve this register's state. Given aretwo controls C1 and C2 that select any of these three operations.use only NOT, AND and OR gates and D type flip flop.
The dynamic resistance for rectifying junctions is given by Rdyn =(dI/dV)-1. For a junction diode having reverse saturation current I0=10-9A, Calculate Rdyn when the diode is biased at V=VF=0.7V, then V=VR=0.5V.
i. The sender sends frames with increasing sequence numbers to the receiver. Only frames received in correct order are accepted by the receiver. ii. The receiver sends a NAK back to the sender when it receives an out-of-sequence frame.
Investigate the effect of varying this ratio on thetransfer characteristics of the CMOS inverter in Fonstad, by sketching the characteristics forKN=50uA/V2 with KP = 50, 100, 250and 500uA/V2. In your sketch do accurate plots inregions I,
