Let us consider a practical example of solid state relay as shown in the figure below. If the output switch is opened or MOSFET is off, then it is said to have infinite resistance. Similarly, if the output switch is closed or MOSFET conducts, then it is said to have a very low resist...
When the core moves away from the center of the transformer, closer to the S1 coil, for example, the S1 coil becomes more strongly coupled to the core, and the induced voltage in the S1 coil is higher than the induced voltage in the opposite (S2) secondary coil. The distance of movemen...
Real inductors have turn-to-turn winding capacitance that acts as if it were a parallel circuit element. The self-resonant frequency (SRF) of an inductor is the frequency at which the inductive reactance is equal in magnitude to the capacitive reactance of the windings. At the SRF, the induc...
DC power is used for modern electronics as well as batteries. The office computer you might be reading this on, for example, plugs into AC power, but it has a type transformer inside known as a switched-mode power supply (SMPS) that converts AC to DC power and converts the DC voltag...
The Manley Massive Passive Stereo Tube EQ is a heavyweight champion in the world of EQs, combining Pultec-inspired technology with cutting-edge innovations. Its passive EQ design, parallel wiring, and transformer-balanced outputs ensure a unique and superior sound quality. While its hefty size and...
theESS Heil Air Motion Transformer™, known for its linear response, low crossover point, and wide dispersion pattern, was used. These were coupled with a high performance passive crossover (Figure 3) and powered with a Behringer NX1000 amplifier, which can output 300 W per channel at 4...
LVDT (linear variable differential transformer)transducers are used to measure linear displacement/position over relatively short distances. They consist of a tube that contains a rod. The base of the tube is mounted to a fixed position, and the end of the rod is affixed to something that moves...

I have two balanced circuits. One is a transmitter and the other is a receiver and both are connected through a twisted pair cable. Now I want to put one more balanced amplifier circuit after the transmitter. What's the problem? Will the ground point for the balanced amplifier circuit be ...
This allows the unprocessed signal to be sent to an amplifier onstage as well as to the PA via the balanced XLR output. This is particularly useful for bass, which allows the bass player to use an amplifier for onstage monitoring, thereby dramatically decreasing stage volume. Bypasses can be...
