TC9400 Wide Frequency Range Pulse Generator

Schematic Diagrams      Comments Off on TC9400 Wide Frequency Range Pulse Generator

The reason why TC9400 V/F converter is very useful in the laboratory are because it’s portable, battery-operated, and low cost frequency source. Both pulse and square-wave outputs are provided by the TC9400. A triangular waveform can also be generated by adding an op-amp integrator. The outputs can be frequency-modulated via… Read more »

Discrete 0.5-300 ms Monostable Multivibrator

Schematic Diagrams      Comments Off on Discrete 0.5-300 ms Monostable Multivibrator

Monostable multivibrator circuit produce a fixed pulse-width when the input is triggered.  The input is fed to CR1, which should be an open collector source since the TR1 would short the input to ground during the active state  appear on this circuit’s output.  The output of this circuit is tapped… Read more »

Sferic Signal Simulator

Schematic Diagrams      Comments Off on Sferic Signal Simulator

Sferic signal simulator is used to produce an impulse  signal which simulates the waveform of a sferic, a radio atmospheric signals produced by a lightning strike. In time domain, the waveform of a sferic signal is a single high amplitude spike. When this pulse is analyzed in frequency domain, it… Read more »
