An analog voice signal that can vary over the range 0-50 mA is digitized bysampling it at 8 kHz. The first four sample values are 10, 21, 36, and 16 mA. Write the corresponding digital signal (a string of 1 and 0 bits) by using a 4-bit representation for each sample.
Due to its wider bandgap than silicon, a GaAs red light emitting diode (LED) typically has a turn-on voltage of 1.6 V. Assuming the maximum allowable current through the LED is 16.7 mA,
A dc shunt motor of 50 hp, 250 V is connected to a 230 V supply and is drawing an armature current of 200 A, and is running at speed of 1200 rpm. Its armature resistance is Ra = 0.2 ohms.
In a particular IC design in which the standard channel length is 2µm, an NMOS device with W/L of 5 operating at 100µA is found to have an output resistance of 0.5MO, about 1/4 of that needed.
Draw a labeled sketch of x(t) over a few periods: be careful, make sure you follow the exact definition of x(t)
