A circuit contains two flip-flops connected to a voltagesource of +10 Volts, each flip-flop draws a current of 10 mA during its operation, if we neglect the power dissipation of the remaining circuit, then what will be the overall power dissipation of the flip-flops.
There is some interest from industry to be able to track the solidification or drying of the paint layer as it happens to ensure correct thickness and material properties. One way to do this would be to measure the changing values of the permittiv..
Design the base-emitter area of NPN BJT so that its transconductance gain is gm=2 A/V at VBE=0.70 V. The technological parameters are as folows: the emitter is heavily doped, the base doping is 5*1017cm-3,the base width is W=0.5μm
Design a V antenna with arm length L=6λ at the frequency 18 MHz , namely find the V angle in degrees , find the beamwidth between nulls. if the frequency changes to 12 MHz , by how many degrees will the peak radiation direction rotate
An AM modulator is operation with an index of 0.4. The modulation input is: m(t) = 4cos (3πfmt) + 2cos (5πfmt) + 4cos (7πfmt) What is the efficiency of the modulator Sketch the spectrum of the modulator output showing the weights of all impulse funct..
Suppose you need an 8-bit counter, and an 8-bit shift register. How would you go about creating these. Could you create them using the counter and shift register you created already.
A calibrated RTD with ALPHA = 0.0041/°C, R = 306.5 Ohms at 20°C, and PD = 30 mW/°C will be used to measure a critical reaction temperature. Temperature must be measured between 50° and 100°C with a resolution of at least 0.1°C.
Assume CMOS inverter propogation delay is 100 pico seconds. Design a one input/ one output pulse generating circuit which will generate 600 pico seconds wide pulse at the output each time the input changes from one logic to another.
A cold heading operation is performed to produce the head on a steel nail. The strength coefficient for this steel is 600 MPa, and the strain hardening exponent is .22. Coefficient of friction at the die-work interface is .14.
A coil of 10H inductance and 5Ω resistance is connected in parallel with a 20Ω resistor across a 100-V DC supply which is suddenly disconnected. Find The voltage across the 20Ω resistor initially and after 0.3 sec.
In a DSB-SC amplitude modulation system, the message signal is m(t)=e^-3t*u(t-2) and the carrier signal is cos(2000pi*t). Find and sketch the Fourier transform of the modulated signal.
A particular op-amp, characterized by a gain-bandwidth product of 20MHz, is operated with a closed loop gain of 100. What is the 3-db bandwidth? At what frequency the closed loop amplifier exhibits a phase shift of -84°
Light traveling in air strikes a glass plate at an angle θ1 = 33 degrees, where θ1 is measured between the incoming ray and the glass surface. Upon striking the glass, part of the beam is reflected and part is refracted.
