MUX BCD/decimal adder, canonical, K -maps, decoder exam questions & answers Binary Coded Decimal (BCD) -what are they -where is it common - ANSWERSa way of encoding decimal numbers in binary where each digit 0 - 9 is assigned a four-digit binary code (nibble) BCD is very common in electronic systems where a numeric value is to be displayed, especially in systems consisting solely of digital logic, and not containing a microprocessor. By utilizing BCD, the manipulation of numerical dat...

Audio signals, such as the output from DVD players, satellite receivers and preamplifers, usually are of what amplitude for input to a TV, modulator or other equipment? - 1 voltage peak to peak The gain of an op-amp is directly, but inversely, related to bandwidth as input frequency increases: - Always Applying positive voltage to the P end and negative to the N end of a germanium diode: - will forward bias it Some variable capacitors are made so the plates interleave. The capacitance vari...

Processor integrated circuit is a super-thin slice of semiconducting material packed with microscopic circuit elements, such as wires, transistors, capacitors, logic gates, and resistors. Usually these circuits are found in microprocessors. ALU (Arithmetic Logic Unit) performs arithmetic operations, such as addition and subtraction, as well as logical operations, such as comparing two numbers to see if they are the same Control Unit The other main component of a CPU, which fetches each ins...
