Current ratio The ratio is mainly used to give an idea of the company's ability to pay back its short-term liabilities with its short-term assets. The higher the current ratio
A 10-kHz tone is used to frequency modulate a carrier; the peak deviation is 75 kHz. Use Carson''s rule to estimate the bandwidth.
the covers of electrical machine are made of
Q. In a CD amplifier,given Rs =4k?, µ=50 and rd= 35k μ. Find the voltage gain Av. The voltage gain, A v = Vo / V i = µR s / (µ+1) R s + rd = 50*4* (103 )/ (50+1)*4*103
1. The coil remaining stationary with respect to the flux, the flux varies in magnitude with time. Since no motion is involved, no energy conversion takes place. Equation gives the
Q. Consider a 1-bit version of the digital comparator shown in Figure. Note that the operation of this circuit is such that whichever output is 1 gives the desired magnitude compar
Q. The response y(t) of a linear system to a unit-step excitation is y(t) = (4 - 10e -t + 8e -2t )u(t). (a) Find the system function. (b) Find the frequency at which the fo
Q. In an AM transmitter that transmits a total power of 1 kW, the unmodulated carrier power is 850 W. Compute the required value of (S i /N i )AM at a receiver, if (S 0 /N 0 )AM
The one line diagram of a simple power system is shown below. The data of the system are given in the table below. (a) Draw the impedance diagram of the system and mark all im
Q. Describe binary number system? The binary number system has a base of 2 with two distinct digits (bits), 1 and 0. A binary number is expressed as a string of 0s and 1s, and
