Tishitu explains
An astable multivibrator is a multivibrator that does not rest in an unstable state like other multivibrators, but continuously switches between two states.
Frequency is calculated using the formula f = 1/T = 1/(ln((Vcc -- Vb) / ( 2 * Vcc -- Vb - Vled)) * 2RC
Vcc = battery; Vb = 0.6; Vled = 2 volt(age drop of LED)
In this circuit frequency is 1/ln((9 - 0.6)/(2* 9 - 0.6 - 2)) * 2 * 37,000 * (10/1000,000) = 2.229 Hertz
Astable multivibrator are free-running multivibrator which have no stable state i.e. they alter between two permissible states indefinitely to result in square wave output. However it is to be noted that, in order to do this, they do not require any external trigger except the DC supply, due to which they fall under the
category of relaxation oscillators.
