Variable-Tone Signal Generating Circuit

Published:2011/4/22 21:40:00 Author:Sue | Keyword: Variable-Tone, Signal, Generating

Variable-tone signal generating circuit can be used in making different types of alarms, and can also in toys which will bring about a lot of fun. As seen in the figure, this circuit comprises relaxation oscillatory composed of unijunction transistor VT1, multivibrator composed of VT2, VT3, and B-type push pull power amplifier composed of VT4, VT5. The selection of component is as follows. VT1: Double-base diode BT33C, the direct current resistance RBB of which between b1 and b2 should be 3~10kΩ. VT2,VT3: 9013，50≤β≤85. VT4,VT5: 3DGl28，50≤β≤65. (In order to guarantee the accuracy of frequency, the parameters of geminate transistors VT2 and VT3, VT4 and VT5 should be as consistent as possible.) Power switch S1: KNX(1×1). Selected switch S2: KZX-1-3W1D(band switch). Audio transformer T: can-type ferrite MTT22, high-intensity enamelled wire L1-2ΦO．13mm, coiled by 380 turns; high-intensity enamelled wire L2-3ΦO.13mm, coiled by 380 turns; high-intensity enamelled wire L4-5Φ0.19mm, coiled by 46 turns. Resistance R12: 1/2 WRJ-type Other resistances: 1/8WRJ-type. (View)

2.5kHz Wien Bridge Signal Generator Circuit
This signal generator is a kind of RC Wien Bridge oscillator Circuit. As seen in the figure, secondary direct-coupling amplifier is composed of triode VT1 and VT1. The input is in a form of bootstrap, making the input impedance much higher to reduce effects on phase-shifting circuit RC. As to the T-type attenuator connected to the output terminal, on one hand, it can meet the demands of output impedance, on the other hand it can reduce the effects that loads have on RC. In this case, the frequency stability of the oscillator depends on that of RC. Because of low-temperature coefficient of RC, the frequency of this oscillator is stable(25℃±15℃, change range ≤±5Hz).

Weak Pulse Signal Amplifier Circuit
The signals of flexible and carotid artery is one of important information sources in pathological researches. The electrical signals,which are changed from pulse signals by high sensitivity pressure sensor signals is very weak, and it can be displayed, recorded or acquired by the computer only via amplification through 69-70dB . Op-amp A1, A2, A3 constitute the typical data amplifier,and A4 forms proportional amplifier. Op-amp F324,which is high gain and low power consumption is used here. (View)
