Low-cost audio power amplifiers often avoid direct coupling of the loudspeaker to the output stage because any resulting dc bias current in the speaker can use up (and thereby waste) its limited mechanical dynamic range. Unfortunately, the coupling capacitor needed can be large! But feedback helps. For example, for an 8ohm loud speaker and fL=100Hz, what size capacitor is needed?Now, if feedback is arranged around the amplifier speaker so that a closed-loop gain Af=10V/V is obtained from an amplifier whose open-loop gain is 1000V/V, what value of fLf results? if the ultimate product-design specification requires a 50Hz cutoff, what capacitor can be used?
a transmission line in a computer network induces a signal delay of 1.25 ns. the signal wave front velocity is chraterized by the equation Vw=c/n,where Vw=velocity of electromagnetic wave front :c=3*10^10 cm/sec is the speed of light in vacuum and..
Design a timer system that has a push button, LCD and RTI. When you press the push button, the timer starts counting each second and displays the seconds' value on the LCD. When you press the timer, the system stops counting.
Develop S-R Latch using 74x74, Would you please show me how to develop and S-R latch using a single 74x74 positive-edge-triggered
The fourier transform of the triangular pulse x(t) is expressed as: X(w) = 1/w^2(e^jw - jwe^jw - 1) Use this information, and the time-shifting and time-scaling properties to find the fourier transform of the signal: y = x, -1
Over a period of 10 seconds, how much charge moves through the element. If electrons carry the charge, which terminal do they enter. How much energy os transferred. Is it delevired to the element or taken from it.
