An amplifier provides 10.5 V output under unloaded condition. When a load of 10-ohm is connected at its output, the voltage drops down to 0.5 V. Find out the output resistance of the buffer that is to be put between the amplifier and the load so that the output voltage across the same load would be 8 V. Given that the input resistance of the buffer is 4 K-ohm.
The built-in voltage of a GaAs pn junction diode is 1.25 V when the diode's temperature is T = 320 K. The cathode region of the diode is doped with phosphorus at a concentration of 1017 cm-3. Determine the required doping concentration in the anod..
A.) We would like to use a series lumped element b to match this load. What is the length of the line where the normalized input impedance is z= 1-jb(d/\lambda). If the rfequency is 1GHz , find the value of the lumped element(C or L).
why sinusoidal wave is chosen for AC fundamentals rather than a simple curve such as square or triangular wave?
Looking at this pattern from left (MSB) to right (LSB), when you see a ‘1' the pulse should be 'ON' for 0.5 seconds. If you see a ‘0', the pulse should be ‘ON' for 1.5 seconds. In either case, the ‘OFF' time should be 2.0 seconds after each ‘ON' t..
For a transformer with a line voltage of 34.5 KV on the primary and a line voltafe of 480V. Calculate Vphase primary and secondary,P,Q, and S for each of the following transformer connections and loads.
Discuss why frequency limits are critical in design of digital integrated circuits. Discuss what is meant by the "complete response" of an RLC circuit. Describe the two "parts" that make up this response.
Consider a portable 20cm2 fuel cell operating at 0.75V, 0.6 A/cm2. Suppose the stoichiometry of the anode is 2.0 and that of the cathode is 2.3. The fuel cell is expected to run for 3 days before being recharged.
What does the DAQ Assistant do How is it useful over the legacy acquisition methods What does FFT stand for and what does it do to a real-time signal Sketch the output of an FFT analysis performed on a 100 Hz sinewave signal at 1 V.
Consider the interval [0,30]: y[n+2] - 0.6y[n+1] - 0.16y[n] = 5x[n+2]. a.) Find zero-state response if the input is x[n]= 4^(-n)u[n] b.) Find zero-state response if the input is x[n]= cos(2npi/6)u[n]
An op-amp is to be selected for an inverting amplifier to be used at dc and very low frequencies. A closed-loop nominal gain of -100 is desired. Specification indicate that the error due to finite open-loop gain cannot exceed 0.1dB.
Important information about Electrical Networks, Engine consumes 5kw of power and a reactive power of 2kvar at current of (3+j2) Amps.
As the ball rises, it gradually loses kinetic energy as its potential energy increases. At the top of its flight, when its vertical speed goes to zero, all of the kinetic energy has been converted into potential energy.
