Three amplifiers with power gains of 15, 22, and 7 are cascaded. The input power is 120 µW. What is the output power of the final amplifier stage?
A long hallway has three doors, one at each end and one in the middle. A switch is located at each door to operate the incandescent lights along the hallway. Label the switches A, B, and C.
An active-loaded NMOS differential amplifier operates with a bias current I of 100 microamperes. The NMOS transistors are operated at Vov=0.2 V and the PMOS devices at |Vov|=0.3V. The Early voltages are 20 V for the NMOS
The charge leaving the positive reference terminal of a voltage source is q(t)= [6sin120pi*t - 8cos120pi*t]mC the voltage source value is v(t)= 160cos120pi*t V. A) Determine the power supplied by the voltage source at t=0
An amplitude modulated amplifier has a radio frequency output of 50w at 100% modulation. The internal loss in the modulator is low. What output power is required from the modulator.
Create and test a function called celsius to convert degrees Celsius to degrees Fahrenheit. The equation for converting temperatures in Celsius to Fahrenheit is T_f=9/5 T_c+32 Display the results as a conversion table for six different temperature..
Assume you buy a 1 kOhm resistor with +/- 20% tolerance in its value. You would like this resistor to consume at most 2 W of power, otherwise it might burn. What is the highest power supply in V you would use to power it
The system contains a door sensor, a window sensor, and a key activation switch. If the switch is on, opening the window will set off the alarm immediately. Opening the door will start a 30 second timer.
There are a number of factors and precautions that need to be considered when developing and introducing new technologies to the marketplace. This is especially the case when this could be a technology without a sustainable known history.
