The voltage and current at the terminals of the circuit element are zero for t<0 and t>40s. in the interval between 0 and 40 s the expressions are
v=t(1-.025t) V, 0i=4-.2t A, 0
a.)at what instant of time is the power being delivered to the circuit element maximum?b.)what is the power at the time found in first part?c.)at what instant of time is the power being extracted from the circuit element maximum?d.)what is the power at the time found in last part?e.)calculate the net energy delivered to the circuit at 0, 10, 20, 30, 40s.
1) in a swamped common-emiter BJT amplifier, as shown below, if Vcc =12 V, R1 =8.2 kohm, R2=10 kohm, Rc = 500 ohm, Re= 1 kohm, Vbe = 0.7 V, and B =100, what is the transistor`s emitter current
HALF-ADDER: S = XY' + X'Y , C = XY (These are the outputs) 1. From the equation given for half-adder, develop an equation for which the half-adder can be constructed just with NAND gates. Draw the circuit as per the equation obtained.
computation with 5% of the code that cannot be paralleled, compute the speedup and efficiency.
A GaAs device is doped with a donor concentration of 3e^15/cm^3 . For the device to operate properly, the intrinsic carrier concentration must remain less than 5% of the total electron concentration
A PWM is used in 8-bit mode to produce a signal with a 1 msec period and 60% duty cycle. Determine the value required for any pre-scaling, and the values for the period, and duty cycle registers. The E-clock is 24 MHz.
A network router connects multiple computers together and allows them to send messages to each other. If two or more computers send messages simultaniously, they collide and the messages must be resent. Design a collision free circuit for a router..
A parallel-plate capacitor has plates of very large extent such that the electric field is perpendicular to the plates. The plates are separated by a distance of 1mm, and a voltage of 100 V is applied to them.
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..
The receiver takes the three received bits and decides which bit was sent by taking the majority vote of the three bits. Find the probability that the receiver makes a decoding error.
