Build a Peak Indicator

When when the condition of point is greater then how much + 4dB, changes for encouraged D1. Its handy around each one siphon with games console with good, around very last amplifiers and also in the alternative use, so that you can most people wanted. Together with the selling prices with outlet, a signify takes place by using concentrations previously + five dB (1. 25V rms). To get adapting to it within amounts of point, we will employ a more trim, in advance of capacitor C1.

Peak Indicator Circuit Diagram :



Parts:

R1 = 10K
R2 = 1.2K
R3 = 220K
R4 = 4.7K
R5 = 4.7K
C1 = 47uF-25V
C2 = 2.2uF-25V
Q1 = BC550C
Q2 = BC550C
D1 = Red LED

Notes:
  • It can be assembled on a general purpose PCB.
  • It can be powered from a 12V-15V regulated power supply.
