Q. Show NPN Common Collector Amplifier?
The common collector amplifier, often called an emitter follower since its output is taken from the emitter resistor, is useful as an impedance matching device since its input impedance is much higher than its output impedance. It is also termed a "buffer" for this reason and is used in digital circuits with basic gates.
By means of nodal analysis, find the current delivered by the 10-V source and the voltage across the 10- resistance in the circuit shown in figure.
Q. Counting to moduli other than 2 n is a frequent requirement, the most common being to count through the binary-coded decimal (BCD) 8421 sequence. All that is required is a four
DESIGN A WIEN OSCILLATOR THAT OSCILLATE AT 25KHZ
Find the maximum frequency of an output sine wave which can be produced at an amplitude of 1.5 V if the op-amp slew rate is 0.5 V/µs.
Design a circuit using op-amp that will reject the 60kHz power line noise and also reject high signal frequency above 800Khz. The stop-band width around the 60kHz centre frequency
