The relative dB amplitude reaponse of an amplifier decreases at the rate of 6 dB per octave at frequencies over 100 kHz. When the input of this amplifier is excited by a sinusoidial voltage of500 kHz and amplitude of 10 V, the output amplitude is measured atand found to be 20V. If the input voltage amplitude is now held constant and the frequency is increased by 2Mhz. What will the approximate output voltage be?
If a particular radar reciever can detect the target using HH polarization at a maximum distance of 10km, find the maximum distance at which the target can be detected using VV polarization. Assume a standard radar equation.
explain how you would modify a 4-bit adder circuit to turn it into an Adder/Subtractor circuit. Explain how your creation would do a subtraction operation. Use a circuit diagram to illustrate. For an Adder/subtractor that works with signed numbers
Assuming that all bias point values are the same for thetransistors in each amplifier configuration, answer the followingfor BJT amplifiers. a) Which amplifier has the highest magnitude voltage gain b) Which amplifier has the highest magni..
You are designing a 2.4 GHz receiver with a 140 MHz IF. System design constraints require that the local oscillator power be minimized to reduce the potential for interference to other systems as well as to reduce the receiver power consumption.
