Suppose you want to build a simple RS flip-flop that is set and reset by negativegoing pulses. All you have are two 2-input AND's and two 2-input NOR's. Show how you would build this odd circuit from the available material.
a) Design a circuit with a single opamp to realize V0=V1-4V2, where V1 and V2 are two input voltages. b) Select the resistor values so that no more than .25W is dissipated in any resistor when the input voltages are no larger than 10V
(a)find the work done in moving a point charge +2C from (2,0,0) to (0,2,0) and then from (0,0,0) to (0,2,0). (b)find the work done in moving a point charge +2C from (2,0,0) to (0,2,0) along the straight-line path joining the two points.
Two dc motors are compared. the first one is a 4hp dc motor which draws a current or 0.7A when the field is connected to a 150V source. the second, a 600 hp motor draws a field current of 5A when the field is connected to a 300V dc source.
A PPL multiplier transmitter is to operate with a 915 MHz output. With a divide factor of 64, what value of crystal is needed
Characteristics of a filter, A filter has the following characteristics: Attenuation = 3.0 dB from 0 Hz to 2 kHz. From 2 kHz to 20 kHz attenuation increases from 3 dB to 23 dB in a straight line when plotted on axes of power in decibels (vertical a..
