Measure Engine RPM With a Microcontroller Coil

Measure Engine RPM With a Microcontroller Coil

Some electrical signals in an engine, such as the ignition signals, change frequency in proportion to the RPM of the engine. A microcontroller, connected to a coil wrapped around an ignition wire of an engine, can be programmed to measure engine RPM by sensing the frequency of ignition pulses. Microcontrollers offer a variety of input …

Eliminate Intercom Noise With a Capacitor

Eliminate Intercom Noise With a Capacitor

Much of the noise that occurs in intercom systems arises from the coupling of DC and AC signals. The elimination of the noise, while retaining the primary signal, is the goal of communication specialists. They use bypass capacitors to filter out the AC noise component of the intercom. A simple intercom circuit uses an operational …

What Jobs Use Oscilloscopes?

What Jobs Use Oscilloscopes?

Jobs that use oscilloscopes are numerous and varied. Oscilloscopes are often referred to as o-scopes and graphically display electrical signals with an added time element on their cathode ray tube (CRT). Most activities can be converted to voltages, and oscilloscopes are versatile instruments able to display extremely small as well as large signals. The scope …

Calculate Steady-State Voltage

Calculate Steady-State Voltage

Voltage levels in time-varying circuits change over time. Time-varying means that the voltage ramps up exponentially until it reaches the steady-state voltage. For this reason, a circuit is said to be in a steady steady when the voltage ceases to change over time. In a simple resistor-capacitor (RC) circuit, consisting of a source voltage (Vs), …
