The Diode only lets the current one way, the cap smooths it out, and the resistor gives you something to take a voltage reading across. it will be kind of sawtooth, but will have the general envelope shape.
For diagram see related links below.

Am demodulator diode detector circuit?
demodulator circuit is a circuit which is used for remove all high frequency components from modulated signal.
How do you design phase shift oscillator circuit with amplitude stabilization?
you ask professor smith from the UNH ECE department
What components are needed to make a light sensor?
well when you talk in electronic subjet we said circuits you need ,but you normally buy a seurity ir detector and put (don´t know this in english contator is mall piece with metal like electric engines and 2 votages gates one is generated for ir detector and the other one is for you main circuit as alarm when the ir detector turn on that part of the contator the both circiuts turns on) both are normally close another is a laser alwais on mirror and circuit who detect when light is off that circuit I know needs diode sensor and chip with gates and true table
What do oscillators do?
Oscillators produce a waveform (mostly sine or square waves) of desired amplitude and frequency. They can take input from the output itself. For a complete oscillator circuit we require a feedback device, amplifier and feedback factor.
How can two square waves be combined in an electronic circuit?
If they are the same voltage a logic gate could combine them in various ways. A ring modulator fed from two square waves would make interesting sounds. An op-amp would combine the waves. A single fet would combine them. One signal flowing from source to drain modulated by the second frequency applied to the gate.
Am demodulator diode detector circuit?
demodulator circuit is a circuit which is used for remove all high frequency components from modulated signal.
Explain about the effect of the time constant RC in envelope detector?
The circuit that generates signal having the shape like imaginary curve is called an envelope detector. The effect of the time constant RC in envelope detector is that the output follows the input curve and the circuit performs like a demodulator.
What is a demodulator?
The process of separating the original information or SIGNAL from the MODULATED CARRIER. In the case of AMPLITUDE or FREQUENCY MODULATION it involves a device, called a demodulator or detector, which produces a signal corresponding to the instantaneous changes in amplitude or frequency, respectively. This signal corresponds to the original modulating signal
What is the use of crystal detector in electronics?
A crystal detector is a diode, often used in non-powered radio receivers. It conducts at a much lower voltage than a typical silicon diode, making it easier to generate the signal amplitude required from the tuning circuit.
Am demodulator diode detector circuit pdf?
diode detector for am demodulation
What is attueneter?
attenuator is a circuit which is used to reduce the amplitude of the signal.
What is demodulation of laser beam?
Demodulation is the act of removing the modulation from an analog signal to get the original baseband signal back. Demodulating is necessary because the receiver system receives a modulated signal with specific characteristics, which must be returned to base-band. There are several ways of demodulation depending on what parameters of the base-band signal are transmitted in the carrier signal, such as amplitude, frequency or phase. For example, for a signal modulated with a linear modulation, like AM (Amplitude Modulated), we can use a synchronous detector. On the other hand, for a signal modulated with an angular modulation, we must use an FM (Frequency Modulated) demodulator or a PM (Phase Modulated) demodulator. Different kinds of circuits perform these functions. A demodulator is an electronic circuit used to recover the information content from the carrier wave of a signal.[1] The term is traditionally used in connection with radio receivers, but many other systems use many kinds of demodulators. Another common one is in a modem, which is a contraction of the terms modulator/demodulator. Many techniques -- such as carrier recovery, clock recovery, bit slip, frame synchronization, rake receiver, pulse compression, Received Signal Strength Indication, error detection and correction, etc. -- are only performed by demodulators, although any specific demodulator may perform only some or none of these techniques.
Can you hook a smoke detector up to a switch to make it sound?
Sure, but what you would have to do would be to put the switch in the TEST circuit of the detector.
What is the input to the op-amp used in the room noise detector circuit?
microphone
What is the function of light detector circuit?
a: its function is to detect a change of light withing its perimeter
The instantaneous value of current in an AC circuit is represented by 150 sin 2π x 30t What are the amplitude and frequency of the AC wave?
The amplitude is 150; 30
Can resonance work in tone detection?
Yes, resonance can work in tone detection. You tune the resonant circuit to the frequency you want to detect and follow it with an amplitude detector. Amplitude above your design threshold value means there is signal frequency within your passband. This is how the original crystal radio worked. The resonant frequency was the frequency of the radio station desired. All other frequencies (radio stations) were rejected by the bandpass filter.
