reliability.Disadvantages:unstable and temperature dependent.Output waveform has
distortions and changes with time.
8)Monostables:It generates the only pulse after switching on, and on continue operation, an
input signal must enter the circuit.The pulse width of the single-short output signal is
determined by R and C values.At the initial state, the transistor T 2 passes the current and T1 is
closed.The capacitor is charged.After Uin enters T1,the T1switches on and the capacitor closes
T2.The capacitor discharges through R and not T1 but T2 continues conducting thanks to the
base current from R1.After the full discharging of the capacitor,T2 switches on again and T1
switches off.
In case of the negative feedback, the midband becomes: larger narrow no matter no
band
