Characteristics of pulse circuit [Copy link]

1) The transistors in the pulse circuit work in a switching state. In most cases, the transistor works in the saturation region or cutoff region of the characteristic curve, so the pulse circuit is sometimes also called a switching circuit. It can also be seen from the transistors used that when the operating frequency is high, special switching tubes are used, such as 2AK, 2CK, DK, and 3AK tubes. Only when the operating frequency is low, general transistors are used.

2) Another feature is that there must be a capacitor (less inductance) as a key component. The generation of pulses and the transformation of waveforms are inseparable from the charging and discharging of capacitors.
