Describe a passive fourth-order Butterworth filter with cutoff frequency of 2000 radians per second and an output resistor of 1000 ohms.
What are the distinguishing features of the response in the pass-band? What are the distinguishing features of the response in the stop-band? What is an all pass filter?
Assume that you are adding two 4-bit numbers. What does a carry-out (in the fifth place) indicate. Does this carry-out indicate something different when we add two positive numbers, a positive and negative number, or two negative numbers.
We have an amplifier with a 1 MHz bandwidth and a 20 mV input signal. The input noise = 1 mV, output signal 6.0 mV, and output noise = 1 mV. Find: (a) SNR at the input (b) ..
A 3-phase, 60 Hz supply and two 3-phase synchronous machines are available. Determine the speed, and a suitable number of poles, for each synchronous machine to provide: a) A 3-phase, 180 Hz supply. b) A 3-phase, 500 Hz supply.
If you have 16 kibibytes of memory plus a few (less than 10) memory mapped devices (assume that each device uses 16 bytes of address space), what should the address size be
Draw the state diagram for a sequence that detects the sequence 0101 using a minimal number of states. The detector should also detect overlapping sequences. Design the circuit using D flip-flops. Draw the logic diagram.
