Ok. So FM signals has a narrower bandwidth than AM signals. But with a subwoofer the power source drawn is through an amplifier. I just joined some reading club and I tailored it to car electronics. The amplifier draws power from the AC/DC, where as the FM signals are drawn to have almost no...
This may be similar to my situation or problem. In Subwoofers, the reduction in bass frequencies is so no power is drwan from the amplifier. In having it efficiently working, does resonant frequency come into play when dealing with minimizing distortion of the FM signals in a subwoofer? Car...
I think the data, video, and communications for a cable such as coaxial cables fall in the same frequency range as RF or radio frequencies. adc, analog to digital converter used would count the bits per second that the cables transmit into the cable system. So if you were on a wireless, the RF...
I find this to occur too, but with electric portable ovens. What I do now is wear slippers to insulate myself from the ground up. And always check to see if the wires have corroded. This is very dangerous. Appliances like this last for one year maybe more, then time to go. On the switches...
Optical fiber is low cost, but technically it becomes harder for longer distances. Class A? Those are amplifier categories. High tech in design as in op-amp, direct couplings or high tech equipment? Fiber Optics is high tech equipment. There is a difference in terminology and use. Only with...
IT says tremendous gains in voltage (up to one million times ) can be obtained in an op-amps. The feedback resistor filters out the signal input on this device, connected to an analog circuit. Amplifiers. Signal amplifiers. Output is connected to a speaker. Op-amp. Direct coupling.
Frequency response? AM has constant wave carriers and different audio signals. Cannot see clearly. Low sound or low volume. Inductive and conductive reactance is zero or cancels each other out. Forward bias. At that point where resistance is zero in circuit. Exact signal impulse, and...
Thanks. I think understand the diagram clearly. There is a voltage input at the base of a NPN transistor. Meaning a plus sign (1) and forward bias through the resistor. Negative would be the emitter. Conventional flow of electric. Positive to negative battery terminals.
