AI Thread Summary
Integrated circuits can select specific frequencies using filters, either digital or analog, to isolate desired signals. Voltage regulation typically involves maintaining a steady output amplitude, which can be achieved through gain control mechanisms. Frequency and voltage are generally independent, allowing adjustments to one without impacting the other. A frequency divider, such as a crystal oscillator with a counter, can also be used for frequency selection. Additionally, voltage-controlled oscillators exist, which can modulate frequency based on voltage changes.

Is there such an intergrated circuit that can select a specific frequency out of a large selection of frequencies and to regulate the voltage.

Frequency slectivity is accomplished with a filter, either digital or analog in nature. Not sure what you mean by "regulate the voltage". Do you mean to filter a particular frequency range of signal (like with a bandpass filter), and then use gain control to cause the peak-to-peak amplitude of the output signal to be some set value?
 
I'm thinking of an ac voltage regulator. since changes in voltage create changes in frequency, I thought by regulating the voltage to one steady voltage flucuation that it would regulate the voltage and frequency.
 
An AC voltage regulator is a plain ol' transformer, at least if you know what the input voltage is.

Perhaps you are thinking of a frequency divider.
Basically a crystal oscillator with a counter network where the divisor can be set by switches.

Voltage and frequency are normally independent quantities.
You can adjust one without affecting the other.

There is such a thing as a voltage controlled oscillator though.
 
While I was rolling out a shielded cable, a though came to my mind - what happens to the current flow in the cable if there came a short between the wire and the shield in both ends of the cable? For simplicity, lets assume a 1-wire copper wire wrapped in an aluminum shield. The wire and the shield has the same cross section area. There are insulating material between them, and in both ends there is a short between them. My first thought, the total resistance of the cable would be reduced...
Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...
I am not an electrical engineering student, but a lowly apprentice electrician. I learn both on the job and also take classes for my apprenticeship. I recently wired my first transformer and I understand that the neutral and ground are bonded together in the transformer or in the service. What I don't understand is, if the neutral is a current carrying conductor, which is then bonded to the ground conductor, why does current only flow back to its source and not on the ground path...
