    The decibel is a logarithmic-based measurement scheme. It is based on ratios of change. Positive values indicate an increase while negative values indicate a decrease. Decibel schemes can be used for gains and, with minor modification, signal levels. A Bode plot shows the variations of gain (typically expressed in decibels) and phase across a range of frequencies for some particular circuit. These will prove to be very valuable in later design and analysis work.
