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 highestmagnitude voltage gain?b) Which amplifier has the highestmagnitude current gain?c) Which amplifier has the highestoutput resistance? Lowest output resistance?d) Which amplifier has the highest inputresistance? Lowest input resistance?
Your design calls for a 4-way multiplexer. However, when you go to the stock room, all you can find is a 2x4 decoder, AND gates, OR gates, and inverters. Show how you can create the 4-way multiplexor with a single 2x4 decoder and the appropriate m..
Show that a linear dependent current source controlled by a voltage appearing across an element in parallel with the dependent source is equivalent to a resistor. Determine the value of the resistance in terms of the parameters of the dependent so..
a low pass first order instrument has a time constant of 20ms. Find frequency in hz of the input at which the output is 93% of dc output. Find phase angle.
A user wanta 6-bit counter that has an asynchrone clear.the user can load it with a value.when activated,it has two modes.in mode 1,it can perform increment by 4,in mode 2 it decrement the value by 1.write the VHDL code for the system.
An amplifier operating from a single 15-V supply provides a 12-V peak-to-peak sine-wave signal to a I-ill load and draws negligible input current from the signal source. The de current drawn from the 15-v supply is 8mA.
To transmit this signal by binary PCM without compression, uniform quantization is adopted. If the SQNR is required to be atleast 43dB, determine the minimum number of bits required to encode the uniform quantizer. Determine the SNR obtained with ..
A distortionless transmission line operating at 125 MHz has characteristic impedance = 40-ohm, attenuation constant = 0.02 Np/m and phase constant = 0.75 rad/m. Find the resistance and inductance per unit length for the line.
Assuming that directions of arrival are uniformly distributed at the mobile, how large is the correlation coefficient for a GSM 900 system between the channel in the middle and the end of the burst when the mobile station moves at 200 km/h
If I have a resistor that is 10 Ohms and has a voltage drop of 4.2 V, how much current is flowing through the resistor?
What is the efficiency of an AM transmitter if it outputs 10 W of power to a 50 Ώ load while drawing 1 amp from a 12
The capacitance of a capacitor formed by two parallel metal plates each 200 cm2 in area separated by a dielectric 4 mm thick is 0.0004 microfarads. A p.d. of 20,000 V is applied. Calculate (a) the total charge on the plates
(a) Three volts is applied across a 1-cm-long semiconductor bar. The average electron drift velocity is 104 cm/s. Find the electron mobility. (b) If the electron mobility in part (a) were 800 cm2/V-s, what is the average electron drift velocity
