Determine the V-I characteristics of a regulated DC voltage supply with its output voltage set at 20 V (no-load) and its short-circuit current limit set at 80 mA. You have a DC supply running in series with an Ammeter and a load resistance of 3K or higher and the load resistance is in parallel with a Voltmeter. Determine the I-V characteristics of a regulated DC Current supply with its output current set at 100 mA (no-load) and its open-circuit voltage limit set at 20 V. What do they mean by these two statements? For example, are they asking us to keep Voltage or Current constant in either statement and vary the Resistance finding the unknown Voltage or Current or what?
Find all values of alpha such that the system is stable for K = 2. If the unity feedback closes around this G(s) and an input is a unit step r(t) = 1u(t), what is the stead-state error, e_ss, as a function of alpha and K?
Assume you have a receiver with an overall noise figure of 23 dB and a bandwidth of 1 MHz. Assuming the minimum acceptable SNR at the output of the receiver is 6 dB, estimate the minimum detectable signal level in dBm at the receiver input.
A noninverting amplifier has a closed loop voltage gain of 11. What is the output peak voltage if the input is 2 V peak to peak?
A GaAs device is dopeed with a donor concentration of 3*10^15 cm^-3, For the device to operate properly, the intrinsic carrier cconcentration must remain less than 5 percent of the total electron concentration.
Explain why the following act lead to hazardous safety conditions when working with electrical equipment. (a) wearing metal rings or bracelets (b) being barefoot,(c) working on damp or concrete floor
1. Determine the peak-to-peak current ripple in the output inductor for a forward converter and determine the output voltage ripple of the converter. We know the following parameters: duty cycle d, input voltage Vin, turn ratio.
The circuit will have as inputs a minimum of two inputs; the binary equivalent of two decimal numbers of not greater than (10,000)10. The circuit will produce a minimum of two outputs, the quotient and the remainder.
How is the problem-solving process different when programming in assembly language versus programming in ladder logic?
Calculate the signal to noise ratio given RMS Noise Voltage = 20mV and RMS Signal Voltage = 2.5V Calculate ETotalRMS given e21RMS = 5V and e22RMS = 7V
Write a C-Program that tells whether or not there are repeated cards amoung a 2-d array[4][13]. It returns "true" if it does. The program needs a function to determine whether or not it has repeated cards.
Determine a suitable sampling frequency. Design a notch filter to remove the 50Hz component, paying particular attention to any assumptions you have made in the design.
Two data streams are coming serially to a system. These two streams are carefully observed and if considering any three bits from each stream, we observe that these two input streams are equal ; the FSM gives a signal to an alarm system.
