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.
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
Q. Describe about transmission-line voltage regulation? The transmission-line voltage regulation (TLVR) is the ratio of the per-phase voltage drop between the sending-end and r
