Find the amplitude,peak-to-peak value, average (DC) value, frequency, period, and phase angle of the following sinusoidal waveforms:a. v(t) =-3V - (12V)cos(2*pi*100t+ π/4)b. v(t )= 3V+ (12V)sin(2*pi*100t+ π/4)c. v(t )= 3V+ (12V)cos(2*pi*100(t+ 0.001))d.v(t) =3V+ (12V)sin2 (2*pi*100t)
Determine the range of DC current that can be applied to coil 2 without saturating the core when coil 1 has a steady 10A DC current in the direction that makes the flux flow CW on the ring . The Current at coil 2 has the same direction as the curr..
The voltage drops across three resistors in series are measured to be 10.0V, 15.0V, and 25.0V. If the largest resistor is 47.0 ?, what is the value of the smallest resistor?
Two LTIC systems have impulse response functions given by h1(t)=(1-t)[u)t)-u(t-1)] and h2(t)=t[u(t+2)-u(t-2)].a) Carefully sketch the functions h1(t) and h2(t). b) Assume that the two systems are connected in parallel.
a) Make a table showing each load and its complex power. b) Determine the total complex power and the overall power factor. c) Determine the magnitude of the total current supplied by the 600V source.
Find the magnetic field intensity using the concept of vector magnetic potential for plane z = 0 carrying uniform current K =Ky ayz.
A capacity coupled amplifier has a midband gain of 1000 V/V, a single high-frequency pole at 10 kHz, and a single low-frequency pole at 100 Hz. Negative feedback is employed so that the midband gain is reduced to 10.
If wind power at this site varies as the ratio of heights raised to the 1/7 power, compute the ratio of power in the wind that appears at the tip of the top blade relative to the power that appears at the elevation at the tip of the bottom blades.
an fm transmitter delivers to a 50 ohm antenna a signal voltage of V(t)= 75sin(10^8 t+2 sin 10^3t) determine(a) carrier frequency (b) Intelligence frequency (c) modulation index (d) Total Power in FM signal
A simple RC filter is to be designed to pass frequencies below a nominal value of 40 Hz. If the attenuationat 40 Hz is to be 5 dB, determine suitable values of R and C for the filter.
In n-channel JFET, Ohmic region is separated from Saturation region by VP so called Pich-off voltage or VGS(OFF). What is the value if IDand VGS at this location and how we can calculate the value of VP from ID and VGS
a.) What isthe minimum sampling frequency to avoid aliasing b.)If the sampling frequency of fs=2500 samples/sec is used how many samples must be taken to give a frequency resolution of 10Hz
Analysing spectrum anlyser output, A spectrum analyzer is connected to an unknown signal. The spectrum analyzer displays the power level of signals in dBm vertically and frequency horizontally. The spectrum of the unknown signal creates the follow..
