I'm transmitting data from a microcontroller to a smarphone mic input and I was suggested to use this circuit to adapt the 5v digital signal: Taken from this tutorial The way I see it R2 and R3 ...
I've the following amplifier circuit: The two BDX77 are actually a single darlington BDX53C (I do not have the spice model for it), and the same for the two BDX78 (a single BDX54C). It sounds ...
Suppose, i have an audio signal source. I want to connect and disconnect it to amplifier electrically (for example controlled by another source, like microcontroller, sensor, 555, etc). I don't want ...
Can an RLC network be defined that would behave in the same way as a theoretical loudspeaker? Since their behavior is frequency-dependent, would the values of R, L, and C also be frequency-dependent?
I have a PA system which is outputting at most 200Vrms AC peak, around 100Vrms AC nominal, from the transformer. The current is around 4Arms. Since the system is comprised of 12 output transformers, ...
