A transistor amplifier stage comprises a transistor of parameters hie = 800 Ω, hfe = 50 and hoe = 20 μS, and bias components and coupling capacitors of negligible effect. The input signal consists of an e.m.f. of 60 mV from a source of internal resistance 2.2 kΩ, and the total load on the stage output is 4 kΩ. Determine the current, voltage and power gains of the amplifier stage.
A tank of fluid employed in a chemical process is being monitoredwith three sensors. The sensors measure temperature, pressure andfluid level. If all the sensor measurements are in the normalrange, the sensor outputs are low.
design and build a rectifier circuit and use its result toturn on led( Use 60 Hz, 0.5 to 2 volts peak as a source, setupamplification circuit if needed to turn on led. use transistor todrive led., and also write concluson and explain the analysis.
A 3-D printer lays down a semicircular arc of positively charged plastic with a radiusR = 3.5 cm, and a linear charge density of Lambda = +1.9 uC/m. After the printer has finished the arc, the stylus moves to the center of the arc.
A gold wire (resistivity of 2.44× 10(-8) Ω·m and a temperature coefficient of 3.4×10(-3) °C-1) with a radius of 0.100 mm has a uniform electric field of 2.50 V/m imposed along its entire length. The temperature of the wire is 50.0°C.
the frequency response h(e^jw) of a length-4 finite impulse response filter with a real impulse response h[n] that the following specific value: h(e^j0)=13, H(e^j3pi/2)=-3-j4, and h(e^jpi)=-3. determine the 4th discrete fourier transform (DFT) of ..
How much resistance is required to limit the current to 3 mAif the potential drop across the resistor is 12V
For f0 = 1/50 and N = 200, write a program to quantize the signal x(n), using truncation, to 64, 128, and 256 quantization levels. In each case plot the signals x(n), xq(n), and e(n) and compute the corresponding SQNR.
A standard D cell flashlight battery is connected to a load of 3 ohms. After 6 hr of intermittent use the load voltage drops from an initial 1.5 V to a final useful voltage of 0.9 V. (a) Calculate the internal resistance of the battery at the load ..
A steel wire 30 ft long, hanging vertically, supports a load of 500 lb. Neglecting the weight of the wire, determine the required diameter if the stress is not to exceed 20 ksi and the total elongation is not to exceed 0.20 in. Assume E = 29 × 106..
Two resistors of resistance R_1 and R_2, with R_2>R_1, are connected to a voltage source with voltage V_0. When the resistors are connected in series, the current is I_s. When the resistors are connected in parallel, the current I_p from the sourc..
If the thermometer is placed in a bath, the temperature of which is changing linearly at a rate of 10degrees/minute, how much error does the thermometer show
Explain why the low value (0) for the 'output' of a digital logic gate is lower than the low value for the 'input' of a digital logic gate (This is the case for CMOS and Bipolar logic). Look at a specsheet.
