This simple circuit generates narrow pulses at about 700-800Hz frequency. The pulses, containing harmonics up to the MHz region, can be injected into audio or radio-frequency stages of amplifiers, ...
In Boost and modify square waves, we covered several methods for conditioning square waves for use with digital signals. In this final installment, we look at 555 timers, voltage regulators, op amps, ...
The behavior of analog circuits can often be characterized by sweeping their inputs with a signal going across a range of frequencies and then observing the output. These sweeps can be composed of ...
