A 10V supply is connected in series with a resistor and 3 diodeswith the output taken with respect to the three diodes together toground. The problems asks to find the value of the resistor provided that the output voltage is 2.4 and the diodes have 0.7Vdrop at 1mA and a 0.1V/decade change in current.
A BJT differential amplifier is biased to have 500uA dc current in each device, β = 100, RC1 = RC2 = 1Kohm, and RE = 3Kohm. Assume ro = ∞. When operating in balanced in, balanced out mode what is the maximum allowable resistor tolerance
design a 3-bit synchronous counter (using only D-flip flops and NAND gates) that produces the sequence 000, 010, 011, 001, 101, 100, 000, etc. whenever the single input is 1. The counter retains its current value whenever the input bit is 0.
A police K-band radar is operating, with transmit power of 1000 Watts and antenna gain of 300 in linear units. The radar unit is designed to detect a target with a radar cross-section (RCS) of 6 sq. meters and its receiver can detect a signal
A mass memory system has 24 address lines and 16 data lines. (a) What is the size of this memory system (b) How many 64K x 8 memory chips are needed to build this memory system
vehicle of mass 1400Kg is traveling at a speed of 50km/hr. What is the kinetic energy stored in its mass Calculate the energy that can be recovered by slowing the vehicle to a speed of 10 km/hr.
consider a continuos LTI system with step response given by ys(t) = tu(t) - (t - 2)u(t - 2). A. Determine the laplace transform X(s) of the input signal x(t) = u(t). B. Determine the Laplace transform Ys(s) of the step response.
a ppl frequency synthesizer has an output frequency of 470 MHz. A divideby10 prescaler is used. The reference frequency is 10 KHz. what is the frequency step increment
A circuit must detect a 01 sequence. The sequence sets z = 1, which is reset only by a 00 sequence. For all other cases, z = 0. For example, for input sequence as follows, the corresponding output sequence would be: x = 010100100
show that for a square matrics the linear dependence of the row vectors imples the column vectors.conversely for a non square matrics either row vectors or column vectors are linear dependent.
