The contects of a six-bit register are initially 100101. The register is shifted four times to the right, with the serial input being 1101. What are the contents of the register after each shift?
1. A signal with a range of 0-12 V is sampled with an 8-bit ADC. What is the change in voltage (delta) between digitized levels 2. Using the SPI, we send three bytes to the LTC2600 DAC. What information is provided in each of the three bytes
b) find nonhomogeneous solution with method of undetermined coefficient with constants evaluated c) combine homogeneous soluton with nonhomogeneous solution to form the general solution calculate the unknown constant in homogeneous part
an inductive circuit takes a current of 10.5 amperes when connected to a 500 volts 50c/s supply. this current rises to 12.5 amperes when frequency is reduced to 40 c/s. the voltage being maintained constant. find the resistance and inductance of t..
Sketch the Bode plot (closed-loop gain vs. frequency, and closed-loop phase vs. frequency) of the amplifier. Label the gains at 0.1*f3dB, f3dB, and 10*f3dB using dB-scale. Also indicate the values of the phases at these frequencies.
In a typical mobile communications base station (or cell site), a radio frequency (RF) signal is amplified in the base station and then sent (over cable) to the antennas at the top of the tower.
Single pole amp. has an open loop gain 10^6 and open loop bandwidth of 10Hz. If the feedback factor =1, calculate the gain and bandwidth after the feedback
Design a vending machine controller. The machines sells coke and pepsi. The cost is 25 cents, accepting dimes and nickels. When a dime is inserted the input D is asserted. When a nickel is inserted the input N is asserted.
Assume a CDMA system has only 4 walsh codes. If the mobile is assigned W4 and receives a data stream of 11011010, what is the output?
A pulsar lies 1000 light years from Earth. The average plasma concentration is 1 el/cc. Using the plasma dispersion relationship for group speed, what is the group delay between a pulsar pulse received at 1 GHz and at 800 MHz
