design a multirange ammeter with ranges of 1-10mA,0-100mA, and 0-1500mA, using a 5mA movement whose internal resistance is 3.8ohms. draw a circuit diagram of the meter.
Prepare an Excel graph showing the individual components and summated resultant waveform of the odd harmonic series resulting in an approximate square wave.
A system samples a sinusoid of frequency 480 Hz at a rate of 100 Hz and writes the sampled signal to its output without further modification. Determine the frequency that the sampling system will generate in its output.
Design a circuit to give uninterrupted 5 V dc power supply with 110 V 60 Hz line voltage as input. The dc output should be available in case of power outage (110 V line supply). In case of line failure, the circuit should switch to backup source t..
The cylindrical coaxial cable with the cross section shown below, has inner and outer radii of 5mm and 15mm respectively. The dielectric parameters are; er=2, signma=5*10^(-10) S/m and Ur=1
determine power and limiting error of the power?
Compute the first 10 samples of the step response for the nonrecursive difference equation: y(n) = x(n) -0.5x[n-1]-0.7x[n-2] Indentify which of the following filters are recursive and which are nonrecursive.
Air is to be compressed from atmospheric pressure at 60oF to 100 psia in a centrfugal compressor (isentropic efficiency about 0.7). The flow rate will be 500 lbm/min. Specify the horsepower required for the driving motor
The toggle switch has been closed for two minutes. During the first 15 seconds after the closing of the toggle switch, pushbutton I2 was pressed four times. Describe what the status of the motor and the pilot light (PL) will be at the two minute m..
Let y[n] = Odd{x[n+1]}, where Odd{f[n]} takes the odd part of f[n]. Determine if this system is a. Linear b. Time invariant c. Causal For each part, either show proof that the property holds or show an example that it does not.
An n-channel JFET needs a NEGATIVE voltage applied to its GATE, relative to its SOURCE. If you have a single POSITIVE supply applied to the MASTER loop of a JFET, the mid point of the voltage divider will also be a positive voltage
A mixer stage has a noise figure of 20 dB. This mixer stage is preceded by an amplifier which has a noise figure of 9 dB and an available power gain of 15 dB. what is The overall noise figure referred to the input.
discuss to describe as best as possible an automatic garage door opener system. You should either use one you are familiar with as an example, or recall the details from one or more that you imagine could be available
