What are the primary charge carriers in an npn bjt? what about a pnp bjt? 2. (10 points) consider a pnp bjt with vb> ve> vc. what mode is the device in? 3. (10 points) what is the primary charge carrier of an n-channel mosfet? what about a pchannel mosfet? 4. (10 points) when the gate-source voltage of an n-channel mosfet is significantly higher than both the threshold and the drain-source voltage, what mode of operation is the device in? 5. (20 points)

Give your knowledge of these things in your paper, you will compare and contrast analog and digital signals to determine which is more reliable for encoding and transmitting information. you’ll compare these features: signal shape numerical values for signal measurements amount of data that can be transmitted energy requirements privacy and security (ability of the signal to be encoded in a secret code) clarity of signal in the space provided, write down what you already know about any of these features. if you’re not sure, write down questions you might have about the features.

Adolphin emits ultrasound at 100khz and uses the timing of reflections to determine the position of objects in the water. part a what is the wavelength of this ultrasound? assume that temperature of water is 20 degrees c. answer in cm

Select the best definition for wavelength. the height of an oscillating electromagnetic wave the rate at which electromagnetic waves oscillate. the distance between two crests of an electromagnetic wave. the oscillations of electric and magnetic fields select the best definition for frequency. the oscillations of electric and magnetic fields. the height of an oscillating electromagnetic wave. the distance between two crests of an electromagnetic wave. the rate at which electromagnetic waves oscillate
