Analog circuits: An analog circuit is a circuit with continuous,
variable signal (i.e. an analog
signal) as resist or opposed to a digital circuit where a
signal must be one of two discrete levels. Analog circuits within electrical equipment can convey/
carries information through changes in the current, voltage, (or) frequency.
At
resonance the impedance of the
circuit is real i.e. means purely resistive only. This occurs because the
reactance of inductor and capacitor at resonance
are equal but oppositive sign and cancel out each other.
In this topic we will see what is resonance
and resonance types i.e. series
resonance, parallel resonance.
And also we will discuss from important
formulas of this resonance.
1.A
Bipolar Transistor is Operating in the active region with a collector current
of 1mA. Assuming that the β of the transistor is 100 and the thermal Voltage (Vt)
is 25mV,the trans conductance(gm) and the input resistance (rπ)
of the transistor in the common emitter Configuration, are
