What are the names of the three regions of the bipolar junction transistor? Why is there a thin region of one material type
A sinusoidal current is zero at t = -0.625 s and increasing at a rate of 8000pi A/s. The maximum amplitude of the current is 5 A. a. What is the frequency of i in radians per second b. What is the expression for i
The signal given is x(t) =cos(440*2*pi*t) +cos(554*2*pi*t)+cos(659*2*pi*t) Find the complex exponential forier series of the signal and plot k vs Ck for k=-1000 to 1000.
Radio Systems, In design of radio systems that incorporate wireless networks, considerations must be taken such as user access, transmission direction, switching and signal strength.

Invesitagtion of Intermodulation through an amplifier, An amplifier is designed to handle frequencies around 9 GHz. The bandwidth of the amplifier is 2 GHz with a center frequency of 9 GHz
Important information about Digital signal processing, (a) Design a lowpass FIR digital filter using "remez" routime in Matlab for the following specifications:
A circular coil of 200 turns of radius a=60mm, total resistance R=2 ohm, and no self inductance is rotated about a vertical diameter with uniform angular velocity =200 rad/s in a horizontal magnetic flux B of 0.25 Tesla.
Explain the function of the HMI in a SCADA system.
The microprocessor then reads the 8-bit data from the dip switch and puts the value in memory starting at location called ‘BUFFER' . This same data is sent to a digital-to-analog converter ( D/A) whose output drives a dc motor.
For the system represented by the following difference equation y[n] = 0.5x[n] + 0.5x[n - 1] find: (a) the transfer function H(z) of the system. (b) the frequency response H(e^jw) of the system.
