A particular electronic signal source generates current in the range 0 mA to 1 mA under the condition that its load voltage not exceed 1 V. For loads causing more than 1 V to appear across the generator, the output current is no longer assured but will be reduced by some unknown amount. This circuit limitation, occurring, for example, at the peak of a sine wave signal, will lead to undesirable signal distortion that must be avoided. If a 10 K Ohm load is to be connected, what must be done? What is the name of the circuit you must use? How many resistors are needed? What is(are) the(ir) value(s)?
A cam is to be desinged for an automated part loader.Using the motion equations,construct a chart that tabulates follower displacement versus time and cam rotation. Also plot this data when the prescribed motion for this application.
If the output of the function generator for a sinusoidal waveform is 6 voltage divisions peak to peak and the voltmeter reads 2.12V, find the volts/div scale that is being used. If the frequency is 1 KHz and the peaks are 5 horizontal divisions ap..

A digital system has a clock generator that produces pulses at a frequency of 16 MHz. Design a circuit (draw the logic diagram) that provides a clock with a cycle time of 250 ns.
An amplifier is to have an input of 100watts. Its effeciency is 75%, what is the maximum ambient temperature wherein this amplifier may be placed with a maximum junction temperature of 200degC and a junction to case thermal resistance.
For a circuit we would like to implement, there are two control signals: x and y. If xy = 01, an 8-bit value R is incremented by 1 and control goes to a second state. If xy = 10, R is cleared to zero and control goes from the initial state to a th..
