1. In Logisim implement an 8-to-1 MUX using 2 4-to-1 MUXes and a 2-to-1 MUX.
2. In Logisim implement an 8-to-1 MUX using 4 2-to-1 MUXes and a 4-to-1 MUX.
3. In Logisim implement a circuit similar to the one in figure 8-10, but which produces output which is the opposite of the input switch (e.g. the LEDs are 0 when the switch is 1, and 1 when the switch is 0). Change the program in the breadboard to match this new logic.
Two short antennas each of length 10cm at the origin carry identical currents of I = 5 Sin (wt). One is in the az direction and the other one is in the ay direction. If the frequency of the antenna is 60 MHz then calculate
1. use microsoft excel to compare costs from at least three different vendors and reasons to accept specific bids.
The stator of a slip-ring induction motor with slip-ring terminals open-circuited has a stator excited from 3-phase source. The rotor is run by a prime mover. What will be the frequency of rotor induced emf at the following speeds?
a binary transmission channel introduces bit errors with probability 0.15.estimate the probability that there are 20
Fourier transform X(w)=Xreal(w)+j(Xi(w)). Determine and represent the signal y(w) that gives the fourier transform of Y(w)=Xi(w)+Xreal(w)e^exp(j2w).
The signal x(t)=10cos(t)+10sin(10t) is input into the following systems: a) \(H(s)=100/(s^{2}+10s+100)\) b) \(H(s)=s^{2}/(s^{2}+10s+100)\) calculate the output for each system.
What fundamental property is used to transmit information through a channel? - Consider a telephone line with a channel bandwidth of 2 kHz and SNR of 40 dB. What is the maximum data rate possible?
The system has total capacitance CT = 1.0 muF (10 ^ 6 Farad) and average frequency in use at 10kHz. The transformation of battery power to power inn the microcontroller and additional components occurs with virtually no losses.
Determine ideal impulse response using inverse discrete-time Fourier transform. An ideal low-pass filter is described in the frequency-domain by
Compare with the result in Figure 13.12b for the dielectric resonator case
a 220v shunt motor driving its normal load draws an armature current of 50A. The armature resistance is 0.25ohm. determine the armature current it will draw when connected to 200V source while maintaining the armature speed and the flux per pole.
A PMOS transistor has Vtp = -0.5V. As the gate voltage vG is varied from +2.5V to 0V, the transistor moves through all of its three possible modes of operation. Specify the value of vG at which the device changes modes of operation.
