A collector modulated transmitter has a supply voltage of 48 V and an average collector current of 600 mA. What is the input power to the transmitter? How much modulating signal power is needed to produce 100 percent modulation?
A coil of 2000 turns surrounds a flux of 5 mWb produced by permanent magnet. The magnet is suddenly withdrawn causing the flux inside the coil to drop uniformly to 2 mWb in 1/10 of a second. What is the voltage induced.
Design a common-emitter BJT amplifier with a gain of -100 (well above 3dB point) and a 3dB point at 100Hz. Assume beta = 100, Ic (quiescent) = 1mA, Vcc=20V. You can omit the output capacitor, but should bypass your emitter resistor.
A signals values have a range of +- 5V and you wish to make measurements with an analog quantization size no mate thatn 5mV. What minimum resolution A/D converter is required to perform this risk
An input signal of 10V at 0o is applied to a parallel RLC circuit with resistor R = 100 , inductive reactance XL = 200 , and capacitive reactance XC = 200 . All three components are connected in parallel to the source.
What is the resistivity of the wire? conductivity? Using the original dimensions of the wire, how much current can you pass through the wire until a 5V signal is degraded 5% or more?
Evaluating Coding Gain, CNR, and BER of a DSSS-CDMA Transmitter, a. A DSSS-CDMA transmitter sends message signals at a rate of 5.0 kbps using a long chip sequence with a rate of 1 M chips per second. In the receiver, what is the processing gain (a..
Two charges are held fixed in an x-y plane. Charge Q=-1*10^-9 C is located at the origin, q=3*10^-9 C is located at (0,2). Determine the voltage (v_ba) between point 'b' located at (3,0) and point 'a' located at (1,0).
1) Find the transient and steady-state responses of the system using frequency domain methods. 2) Find the forced and natural responses of the system using frequency domain methods. 3)Find the 0+ conditions for the system's step response and impulse ..
